>> I didn't find the chats/discussion UI at all clear initially, but once I'd had it explained to me, I could see what was going on.
This is an example of how bad it is: you had to have the chat UX explained to you. Combined with MS cramming as much crap into teams as possible and trying to tie you to their other products with integrations that barely or rarely work - and the AI features are terrible (and yet another MS AI offering called Copilot?). It really is that bad and I'm glad I no longer have to use it.
