Here's a list of features implemented in this stage.

Most notably, now my app uses persistent local storage (IndexedDB) to improve its performance and allow for the required folders functionality. That includes messages, groups, users, and downloaded files. Unfortunately, that required a lot of work and refactoring.
Hip Hyena Jun 22 at 01:14
Required features

- Mobile version, with support of single-column interface. Context menus are opened via long press. Media viewer supports swipe gestures.
- Emoji/stickers/GIFs panel. Trending stickers and stickers search.
- Recording voice messages with the proper "echo" animation.
- Global and local search. Note: there's a slight issue discovered after the end of contest, which prevents messages from showing up in the global search results.

Reward features

- Shared media panel. In addition to Members, Media, Docs and Links tabs added previously, Audio tab now works too, with playable audio files. Audio player at the top of message list. Files can be downloaded now.

Transferred size при первом старте: 347КВ.
Transferred size после перезагрузки страницы для залогиненного аккаунта: 230КВ.

Скорость работы приложения оказалась существенно ниже ожидаемой. Кроме того, выявленные серьёзные недоработки как для мобильных, так и для настольных ОС, не позволяют работе занять более высокое призовое место. 
В приложении также были учтены не все замечания по итогам предыдущих этапов – некоторые выявленные ранее проблемы по-прежнему воспроизводятся. В ходе тестирования работы обнаружены:

1. Критические недоработки:
– Полностью сломана прокрутка в Chrome на Android – на некоторых экранах едва заметен слайдер справа, удерживая который, можно прокручивать экран;
– При логине в аккаунт может открываться случайный чат / канал;
– При открытии вкладки Trending Stickers сильно уменьшается производительность;
– Чаты открываются со смаргиванием, прочими визуальными искажениями и заметным снижением производительности приложения на Android (Chrome);
– Вёрстка на Android (Chrome) ломается простым набором текста;
– Из-за проблем с прокруткой на Android (Chrome), отправка фото становится невозможной – при появлении окна с заголовком нельзя скрыть окно или прокрутить его до кнопки отправки;
– На Android (Chrome) при попытке отправить файл, выбранный файл не отправляется, набранный заголовок не отображается;
– Отправленное голосовое сообщение не воспроизводится до перезахода в чат на Android (Chrome);
– В Safari не работает запись и воспроизведение голосовых сообщений;
– В Safari не поддержаны GIF – отправленные GIF не проигрываются, вместо них отображаются зелёные пузыри даже после обновления страницы;
– Не реализован поиск по сообщениям из строки поиска над списком чатов;
– При вызове контекстного меню на iOS (Safari) выделяется весь экран;
– В открытом чате могут не появляться входящие сообщения до обновления страницы на iOS (Safari); 
– После получения нового сообщения чаты могут не вылетать из архива.

2. Прочие недоработки:
– Некорректные сигналограммы голосовых сообщений – практически всегда отображаются почти прямые линии;
– Бокс подсказок стикеров остаётся на экране до обновления страницы на Android (Chrome);
– В альбомной ориентации в панели стикеров доступны только эмодзи;
– Часть контекстного меню может отображаться за пределами экрана на iOS (Safari);
– Контекстное меню иногда не вызывается до обновления страницы;
– Видео отправляются только файлами;
– При нажатии на поле ввода смаргивает верхняя часть интерфейса приложения на iOS (Safari).

3. Недоработки второй части задания:
– При просмотре медиа в галерее из общих медиа отправители Undefined NaN;
– Существенные проблемы со стримингом;
– В архиве доступен вызов нескольких контекстных меню;
– В папках не поддержано закрепление чатов;
– Объяснения в викторинах доступны к просмотру лишь один раз, для повторного вызова требуется повторный вход в чат;
– Невозможно скачать медиа из просмотрщика;
– Невозможно отменить загрузку файла;
– Нет вкладки Audio в Shared Media;
– Не реализован стриминг видео на iOS (Safari);
– Перемотка в стриминге реализована только по загруженной части аудио;
– Могут подсвечиваться открытыми несколько папок одновременно;
– Невозможно проголосовать в созданном собой опросе;
– Не обновляются результаты проголосовавших в опросе до обновления страницы.

No play voice and Music. Bad responsive

Hip Hyena Jun 22 at 00:14
There's indeed a problem with playing audio files in Firefox, but voice messages seem to be playing fine.

The responsiveness issue shown on the screenshot occurs only on devices with screen width between 600 and 900 pixels.

Nevertheless, thank you for your report!

layout almost everywhere does not match, for examples audio in chat in the wrong color, in the sidebar 4 pictures instead of 3
sidebar does not open well on a 2k monitor, leaves the screen
sidebar content blinks
some dialogs simply stop loading for unknown reasons, chat, avatars, sidebar freeze
the sidebar constantly closes if you switch to another dialog
when the audio ends - it does not switch to next and also it freezes as if it is still playing in the sidebar and topbar
switching between dialogs slows down if you open dialogs quickly - the delay can reach 3 seconds.
ripple effect slows down, works with a delay and not always smoothly
chat scrolling slows down
media viewer animation is bad for chat and sidebar photos, and no reverse animation at all
Chrome 83.0.4103.106, Win10 64bit, res 2560x1440
Hip Hyena Jun 22 at 12:55
Thank you for your detailed reports! Most of your notions are correct, so I will comment only those I don't fully agree with.

- "the sidebar constantly closes if you switch to another dialog".
That's done by design: in my opinion, right sidebar is modal to the current dialog, so it should be dismissed when dialog changes.
Captain Awesome Jun 22 at 12:37
avatar icon is not displayed in saved messages
during the hour of testing, the client freezes 2 times
the media in the dialogue blinks when switching between dialogs
when open a dialogs - the content in the chat jumps
some media in the chat without loaders and a white background is applied, it loads for a long time if you scroll the chat up
when you click on the button in the test to continue testing, nothing is updated, and you only need to refresh the page.
double scroll in forward section
audio streaming does not work correctly, you can’t click anywhere to listen to a song, just wait until it downloads and then you can switch to that chunk
Chrome 83.0.4103.106, Win10 64bit, res 2560x1440
Hip Hyena Jun 22 at 13:00
- "avatar icon is not displayed in saved messages". That's by design. This is the same behavior as in existing native clients.

I should note that the most freezes related to file loading are caused by the fact that right now my app is only able to download files sequentially (which is major flaw by itself) and is not able to cancel downloads that become unneeded. This bit of information may help with testing and finding more problems.
Captain Awesome Jun 22 at 12:37
many service messages are not displayed in the dialogs list, calls are one of them
GIFs are wrong, square and loaded too long
cant open a set of stickers from the sidebar.
sticker panel slows down
pop-up stickers from the chat doesnt open
emojis are not displayed in the input line
stickers in the sticker panel load too long and are not animated
stickers in chat are not animated, they work only if you hover over them.
when viewing the dialog history, for example, the Telegram Party group, there are leaks memory everywhere
big memory leak, managed to dial 11GB in chrome

- "GIFs are wrong, square and loaded too long".
I'm not sure what you mean by "wrong, square". While GIFs indeed can cause a long delay before fully loading, their aspect ratios should be correct.

- "stickers in chat are not animated, they work only if you hover over them."
That is the same behavior as in the second stage. It's done this way to improve performance. Browsers are usually not very happy about playing a lot of SVG animations at the same time.

Not sure if your comments about memory leaks are entirely valid. App heavily relies on in-memory caching, so it can use a lot of memory, but it's not "leaks" per se - all cached data is not wasted, but used for faster loading.

Anyway, that was very useful and in-depth investigation, that's a lot of good work. I'm very grateful to you for that!

1. Если нажать на поиск несколько раз, приложение превращается в тыкву - https://filebin.net/p6vmau5coa05ogyq/1.mp4?t=0z4wxdla;
2. Глобальный поиск не работает. Групповые чаты во вкладке recent отображаются некорректно - https://filebin.net/p6vmau5coa05ogyq/2.mp4?t=0z4wxdla;

Спасибо за информацию об ошибках! Справедливые замечания. Проблему с глобальным поиском я уже упомянул в комментариях к работе.

&Mobile test
Xiaomi Mi 8 Chrome:

the mobile version is working terribly
scrolling chat or dialogs doesn't work! (at all)
almost all animations freezes
when adding archive chat the context menu does not disappear
stickers are very slow
search by date in chat works
no private search results in new page
a lot of content just doesn’t load, layout is very bad, video and screenshot added to the channel.
when you open a general search you get a white screen, watch the end of the video

Thanks again for your testing! Although I would be even more grateful if you used less subjective comments (like “bad” or “terrible”), as they won’t help me to improve my work.

Unfortunately, I can’t check all those assessments, as I don’t have that particular device. I should note, however, that I don’t see what makes layout “very bad” on the video you provided.

Other than that, your feedback is very valuable and I hope I will get a chance to improve mobile performance in the future.
Captain Awesome Jun 23 at 16:05
Well, if that offends you - im sorry.

The minimum requirements of the third stage indicate that Chrome and Safari should work flawlessly. Unfortunately, your chrome doesn't work flawlessly. But even if the scrolling worked, it is still far from flawlessly. For 21 days, you can definitely find an android. At least from friends, even from relatives or just use the simulator. That is, you continued to carry out the remaining tasks, without putting the main ones in order. As in principle, many other participants. Just the motivation of the participants to complete all the tasks is not entirely clear if all this works in this way and is not a flawlessly implementation. Therefore, I expressed my comments, but I understand you and in the future I will try not to offend anyone, only the specifics of the work.
with love <3
Hip Hyena Jun 23 at 17:44
I don't find your comments offensive at all! In fact I mentioned multiple times that I find them very valuable and indicate things I can improve. Sorry if I haven't made it clear enough.

At the same time I don't think calling some behavior simply "bad" or "terrible" is very productive: it doesn't point out the exact issue that should be fixed.

Same goes for discussing if some issues were caused by insufficient testing or motivation. I'm sure all participants are able to decide how to prioritize different tasks by themselves. I would prefer to keep this section dedicated only to specific issues (and, again, I'm very thankful that you're providing such a detailed list of them!).
Captain Awesome Jun 23 at 16:05
In any case, I wish you good luck and I will check the safari + ios soon. I will also check the work of all other participants, just so that the participants, as well as the judges, notice a little more things.
with love <3
Hip Hyena Jun 23 at 17:45
Thank you so much! Looking forward for the new reports. Both iOS and Android were tested extensively, but I'm sure you will find all those pesky flaws and bugs :)
Captain Awesome Jun 23 at 20:51
when you login to the application, the number keyboard does not close, the screen is lower because of this and the white indent is on top. immediately opens the search (made a screen)
double scroll in iphone in dialog sheet
the dialog in the iPhone switches with a delay after clicking on it
the scroll on the iPhone also does not work normally, after 10 seconds it just stopped working, it helped reload the page, after that within 5 minutes the scroll stopped working 10 times, always have to reload the page
when the scroll hangs, even the page refresh takes a long time, you need to wait 7-10 seconds.
when you call the context menu in the dialog list - all content is highlighted in blue
the scroll jumps when scrolling the chat up 3-5 times, also in some dialogs it jumps down. recorded a video
if you scroll through the history of 2-3 screens at the durov’s channel, then when you exit the dialog and go into another, the delay is 5-6 seconds when switching

Thank you for your feedback! It's much appreciated!
Captain Awesome Jun 23 at 20:52
the stickers don't seem to work in safari at all. webp ?
recording voice messages in safari ios doesnt work, voice message playback doesnt work too
if you scroll through the chat history quickly up, then while the messages are rendered and you can see, you need wait a few seconds
the scroll in the dialog list stops working for 2-3 seconds when you release it
If you go to the dialog, after that open the search, then click the up arrow icon on the keyboard, then you exit the search and click exit to the main menu, where the dialog list, a bug will occur and the main search will open instead of the dialog list.
if you go into some dialog, open the emoji panel of gifs/stickers, then immediately switching between the dialogs will be too long. from 5 seconds. only refreshing the page will help

Completely irrelevant dialog list. It shows channels which I didn't subscribe but doesn't show peers which I had conversation with.
Hip Hyena Jun 28 at 19:14
That’s very strange. Did it happen right after the first launch? If you can, try deleting IndexedDB in your browser’s console, and report if this problem persist.
Posh Owl Jun 28 at 19:18
After IndexedDB deletion it goes well, thanks.
My device has a high DPI and I've experienced the following issues:

- The animated emoji on the login pages are cut off at the top
- I have quite a few folders and they don't seem to be scrollable (can't access the last folders)
- When logging in it said it sent me an SMS but actually it just sent a code to my Telegram account
