Cannot join meeting.

Hi, I have a trouble with teams. 

Whenever I try to enter a meeting via a web link I get redirected to the calendar. 

If I try to enter the meeting using code and password I still cannot enter the meeting, but instead of redirecting me to the calendar I got an error message instead. 

Down in the bottom right corner, the message says "Cannot return null for non-nullable field AuthenticationUserProfile.upn".

Can anybody help ?

      In case anyone else runs into this issue, I was able to fix this for a user by clearing all cache and cookies in Chrome
