New Teams becomes unusable with authenticator accounts

cshawaus Same here. After switching to the "New Teams", hoping it might catch up at least a bit with Zoom in terms of performance and usability, the only effect I noticed were different colors, slightly modified buttons,... and the total loss of any chance to log into client environments. 

Authenticator would keep asking for  the two digit code and always claim that it did not match. Fortunately, it is possible to switch back to the old Teams (which seems to be the best function of the new Teams). After that, the codes were accepted again.

Seems almost like Microsoft has given up on innovation and professional software and is sure that many CIOs out there just look at the license costs and don't care about the time their users spend on bad software.
