Phew, only those two things? How about not being able to copy stuff from chat (for some reason this does not work since Skype for Business times)? How about being kicked off from the current chat if one dares to open MS Word/Excel from within the chat? And that's just the beginning of the annoyance.
But, luckily, we can easily integrate our chat with MS Stocks application, and, even better, with MS Power BI!
I have always impression that MS employees cannot use Teams, otherwise they would have noticed that something gone really wrong here. On the other hand, those are people who gave the World the (in)famous Windows Millennium Edition, so everything is possible.
