Several months ago, I switched companies that I work for. This morning, I am working from home and wanted to start Microsoft Teams flatpak on my Pop-Os! desktop and found it would not let me sign in with my new email address.
The application is set for a single user and I could not find a way to, “sign-out”. My solution was to go into the /home/.var/app directory and rename the existing com.microsoft.Teams directory to something else, then restart Teams. This worked. A new config directory was created, I was able to sign in with my new credentials and all is good.
