I’m back.
Basically, my issue is when trying to compose a reply the keyboard does not work. It’s visible but non-responsive, and the cursor is static (visible or invisible, depending on when it was invoked) rather than flashing.
This only seems to happen “sometimes” with the app. By that I mean it’s happening for me now but there was a period yesterday where it wasn’t happening (maybe?), and then of course it was happening immediately after I installed 1.4.1 that fixed the white screen issue.
Videos (in the periods where nothing seems to be happening I’m actually tapping the keyboard!)
Hopefully @team can learn from this most unfortunate series of events.
