Notifications are not enabled yet. You have to open the app and check for new messages.
You will experience lag, invitations that don't complete, invitations that complete more than once, slow message sending, message loss, repeated messages, and other oddities.
Possible Solution: Delete the chat and restart it. Not the contact, just the chat. Swipe it to the left and tap Delete.
Some features in the UI do not function yet, specifically auto-away presence detection, and notifications bubbles for new messages.
