Buggy. Can't make any calls. A group chat with 5 people is stuck in permanent call mode. But none of us are able to join the call. We can't make any new calls or "join" the current one. We all have a green "join" button that just doesn't go away. We have left the group, got added again, deleted the app, reinstalled, tried phone app, tablet, apple, and laptop. Nothing works were are all just stuck.
