Special appfolder is sometimes named Graph

Expected or Desired Behavior

According to the documentation at https://learn.microsoft.com/en-us/onedrive/developer/rest-api/api/drive_get_specialfolder the special appfolder should be named /Apps/{Application Name}

Observed Behavior

For some users the appfolder is named /Apps/Graph even though the app name is not Graph.

For users with the appfolder named Graph the create subscription request fails. The create subscription request for the resource /me/drive/special/approot fails with 503 and the message [Status Code: ServiceUnavailable; Reason: User content migrated. Cannot access disabled item.]

Steps to Reproduce

This happens for some of our users, but not all. I have been able to reproduce it on one onedrive-user that i have personal access to.

Does anyone have any idea how to resolve this? OneDrive is unusable for 50% of our users at the moment.
