Hi @Roger Roger
I would recommend opening a ticket with Microsoft in the Admin Center.
You can do this by going to:
1) https://admin.microsoft.com/Adminportal/Home?source=applauncher#/homepage
2) Go to the bottom right corner > Help & Support
3) Type in your issue with Microsoft Teams
4) Press Contact Support underneath suggested solutions.
5) Await support from Microsoft.
If this is helpful please accept answer.
