HeyHey16K​ Ugh. I’m sorry you’ve been caught between support organizations, obviously that isn’t the experience we want. Ownership can be difficult to isolate when macOS, Platform SSO, FileVault, and MDM behavior intersect. We are sharing your question with the PM owner of Apple in the Intune prodict group. If you can share both case numbers with him privately, he can ask Support to coordinate the escalation and ensure both teams have the combined diagnostic information. Good luck.
