I’ve been having issues with the tracker not properly starting a new session when I trigger a new round of play and I now have a good reproduction case for it. Basically the new session fails to start and session tracking generally doesn’t work if you are in a group and you aren’t the creator of the group. It seems 100% reproducible.
So the issue can be reproduced if you get an invite from a friend and join their group and then start a new round. In that case the new session popup window doesn’t appear and the session tracking widget generally can’t be activated.
