Switching to NEW Teams error message "Your admin has restricted access to the new teams"

Hello Team,

On Teams Admin Center 365 we have enabled the Teams update policy for the Global/Org Default to New Teams Only but some users are getting "Your admin has restricted access to the new teams" window when they click the toggle button to try new teams. When they try to switch back to classic they are getting "Your org is installing the new version of teams. We'll let you know when it's ready".

I have checked:

- user account has license and Teams is enabled in Apps

- user account has classic teams running

- verified that the update policy is set to the account

- user can access teams web version and can switch to New Teams

- under apps and features I can verify that New Teams is installed

Are there other recommended troubleshooting steps? (clearing cache or reinstall?)

Thanks!
