Enrolling Microsoft Teams phones and Microsoft Teams Rooms on Android in Microsoft Intune

Fantastic article, very detailed and on-point with what im trying to accomplish atm.

We have several Poly Studio X70 devices which im connecting into Teams, but despite following the guide above and several similar ones online, im unable to get the devices to show any interest in enrolling into intune, they sign into teams successfully and work as we want them to, but they only every show in Azure as registered, with no MDM. 

Im sure im missing something very obvious, but so far its escaping me. I have a support ticket open with MS, but waiting on an engineer to be assigned atm, in the interim, anyone have any suggestions 🙂
