I am facing an issue with cross-tenant file sharing in Microsoft Teams. I have two tenants, tenant1 and tenant2. A member of tenant1 has been added as a guest in tenant2. Despite having the necessary permissions verified in OneDrive, when a user from tenant1 attempts to open a file shared in Teams by a user from tenant2, they encounter an "Unauthorized" error.

I have attached screenshots for reference, confirming that the member from tenant1 has the appropriate permissions through the sharing link in OneDrive.

This issue is hindering collaboration and file access between the two tenants.
