Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello @David Moser
Thank you for contacting Microsoft Forum.
It's unfortunate that you are trying to upgrade from basic to premium and it fails due to portal get stuck.
I would like to share with you workaround to apply:
- In the same browser close other tabs that you are not currently using.
- Run it in Open Microsoft Edge InPrivate (Ctrl+Shift+N) or Chrome Incognito. If it fails,
- Try a different browser. If you're currently using Edge, use any other browser you.
After applying the above workaround and it ends in vain, please check the health service of your tenant by following steps:
- Open the Microsoft 365 Admin Center.
- Navigate to Health > Service health.
Check for any active advisories or incidents.
Let me know the result; if the issue sticks so that I may assist you further. I'm looking forward to hearing from you.
