Microsoft Teams "Join Now" button has suddenly turned gray

Hi, 

I can no longer attend any meetings due to the join button.

I uninstalled a installed again the App Teams but doesn't work. 

From the Web App it works.

What can I do?

Hi @marcopellizzoni   Usually that happens when an audio option is not selected in the opening screen.  As you can see in this example, I've chosen Computer Audio so the Join Now button is available.
