I am a consultant and am setup as Guest on a dozen client/tenants with Teams. I have noticed two recent changes in Teams behavior.

  1. Regardless of which tenant I am connected to, I see real-time popup notifications (on both PC and phone) from other tenant chats. (This is a GOOD thing!)
  2. I have several different PCs going at the same. It's not unusual for chats to not update on all machines. Sometimes I need to restart Teams for the chats to show all current messages. I've taken to running Teams from within Edge to alleviate this problem.

Just wondering if anyone else is seeing this.
