A non-profit I help out sometimes, was affected, and I have to say the emails were not that clear. Because it's hard to figure out what is part of a license, the free tier etc. I let it lapse, because we migrated of Office, but apparently the license also applied to Intune.

Fine, so I bought licenses but apparently Microsoft deletes "some" of the data. All groups were still there, users and the device ids.. but not the devices themselves. I could see all devices associated to a user but couldn't recreate or restore them in device management. Thus, I had to re-enroll multiple devices. Will migrate off Intune in the future, since it's garbage but haven't found a good alternative for Android devices yet.
