So, I had this exact same experience, until IT turned on whatever group policy allows you to see the New Teams toggle switch. [1] You might still be on the “old teams”. In classic Microsoft fashion, it’s 1000x more complex than it has to be.

Guess what? It still sucks. I still hate using it. I still do less work because of it. Can you scroll back thru messages without seeing a 10am one loading spinner every 15 mess ages? No. But it’s faster… in the general sense!
