Hi Alexey

1. I was referring to Protean (Dark Mix) only!! You were testing on Lucid design which is OK regarding position of the message input field. So your answer is irrelevant. I can assure you that this is not cache problem!!! When I revert Messenger to previous version the position of message input field is OK.
2. When on Messenger page (.../una/page/messenger ) on Android phone and Chrome browser user have list of previous chats with other members. When any of chats taped chat won't open.
3. I was clearing cache from Studio, restarting apache, restarting php-fpm, manually cleared cache and cache_public folderers
4. I will PM you site address.

Tested on Android 10, Chrome 96.0.4664.45

Best regards

Mayki
