No "All chat messages" on mobile. UI bug Nr 1
You can't access the message list with all messages on mobile phone if your your screen resolution is full-hd or lower. A workaround for some devices is holding the phone in landscape orientation. This is a really old bug preventing users from communicating with eachother and leads them to using WhatsApp and other off-site messengers.
Steps to reproduce
You can use the developer console to set your desktop browser to a mobile screen resolution.
Click on the chat button in the menu.
Select "Alle Nachrichten"/all messages.
There is just "Neue Nachricht"/new message visable.
What is the current bug behavior?
The list below doesn't get displayed when screen width is the width of full-hd or lower. Users can't access chats - especially self created group chats this way.
What is the expected correct behavior?
Like in horizontal orientation the list should be displayed also in vertical orientation.
Relevant error messages and/or screenshots
Maybe?: Check if there is a pixel/ratio condition for screen width. Try to set it lower. Check if the list still gets displayed correctly.
Be careful: In portrait mode, the conversation list is scrolled down on every page refresh. On some cirumstances, the current conversation is overlapping the conversation list.
