Conversations involving multiple participants, allowing collaboration and information sharing in Teams
I noticed the exact same thing and it's hugely annoying. Such a small "feature" that is quite useful. Why always have to go back to the main Teams window to see which one of the popped-out individual chats has new replies?!?! Talk about going backwards. Start with the same feature set that folks are used to, then add new ones vs taking away existing ones w/o enhancing. I already submitted feedback/request to have it enabled again, but we'll see if it happens or not...
