The contest task is not completed. Unfortunately, the speed of the app is below our expectations. The design of the app does not comply with the provided mockups in many aspects.

Other issues:

– Photos and files cannot be downloaded, no viewer for photos.
– Shared Media section is not implemented according to the provided design guidelines, the links tab is broken.
– The second check for read messages doesn't appear in chats, only in the chats list.
– Messages are displayed above the most recent message in the chat when they are sent.
– Not possible to open messages found in search. When searching for messages in groups from the left sidebar and then clicking on search results, the chat with their author is opened instead of the group.
– Missing names and profile photos for group members.
– Apple emoji not supported.

Hi. Thank you for have a look! I've checked with 2 phone numbers in Canada and Russia and everything just fine.
Your phone number looks too long. What country code are you using?

no nicknames in groups, channels, layout and fonts are different from mockups, chat messages should start at the bottom, and not at the top, the screen attached. chat history looks very bad. no new emojies. no nicknames in channels, no media viewer, no smooth animations, no sticker panel animation, right bar is so laggy, without channel/user desc/contacts. no chat popups, online status without last seen, no virtualization, no active dialog background, the file can be downloaded again if it has already been downloaded, and many more things :(

+video, but no default player, and no progressbar on selfie circle video.
+audio is too working, but player is bad
+media upload popup
+new line by shift enter
+text input before clicking on the field

HI! Thank you for such a huge feedback! Yes, you are right, there are a lot of gaps in layout. The main reason of that is I've spend most of the time on replacing tdweb library). Also I've implemented many small things like notification in browser, or mute video by clicking on duration. Almost all updates or textEntities supported as well. Could you pls share video where I can see lags with right bar?
