When I hit enter to post a message in our small group discussion thread, the screen goes blank except for the enter button at the top of the screen, and the only way to get back to the discussion is to close and reopen the app. About 80% of the time this also deletes my comment and I have to retype it. I’ve had to retype and enter my comments multiple times. I can try to take a screencast of it if you want me too. I’m using an iPhone with the latest software update
