I’ve only guaranteed support for Firefox. The sources are not minified/bundled/gzipped/cached, so there's plenty of room for network improvements.

KNOWN ISSUES:
- sign-in country select is useless (user must type in country code)
- phone number is not formatted
- missing some subtitles for authentication code page
- avatars are not loaded
- shows all discovered chats, not just the joined chats
- some messages types are not supported (i.e. link, photo, video, sticker)
- in group chats, avatars and usernames display for all incoming messages
- missing chat date separator
- ripple doesn't start from click location
- icons not loading in Chrome
- bubble tails not working in Chrome
- long user / group name on forwarded messages should not wrap
- "Saved Chats" is not named properly
- message timestamp is not placed in bottom right when text is wrapped
- no app loading indication
- missing read receipts on messages

It seems the app is not automatically taking new users to the sign-in page. You can manually trigger sign-in via the URL:

For testing purposes, you can navigate the sign-in flow by using the left and right arrow keys.

I've continued developing and fixing features, if you'd like to see the latest version head here:

The submitted app has numerous bugs on the login flow: clicking on any country closes the selector. If a phone number is entered manually with a prefix, the 'Next' button doesn't appear, pressing Enter also does nothing.

We were unable to log in due to these bugs.

app is broken; paths for part of scripts is broken, so does not load and work correctly

Icons are missing.

It scrolls to the middle of the chat when I open a dialog.

If you open a dialog that has a forwarded message from a channel, it will show that channel as a dialog.
