iOs 16.5 Microsoft Teams not working anymore since log off/log in

Hello, Work upgraded the Teams at work and I was asked to log out and log back in with my new credentials on my iPhone. It does not work anymore and IT contacted Microsoft and MS told him I had to speak with Apple. I am in the Beta Developer program for iOs. Teams worked on my iPhone prior to logging off and redoing a login with new credentials.

This Teams works on my PC and my MAC computers.

Any help is greatly appreciated.

Thanks,

Luke
