I suspect this is already a known issue, but don’t see it listed.
The recent update that gives improved chat to mobile users fully broke the Steam/PC version.
Since there’s no “mobile keyboard” popup on PC, we’re left with uneditable text.
- can’t move the cursor with clicks or arrow keys
- chat line doesn’t scroll, so everything typed past the end of the line is not visible
- line contents aren’t cleared after pressing Enter, and need to be erased manually
