I’m trying to join a session and it’s not letting me

I submitted the what’s your why form and it won’t let me book the first free session?

The chat screen is super slow. My typing is always delayed, and I can't scroll in real time.

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
