The enrolment problem is a known issue with the current version of Android Mobicontrol Agent (v14.4.1) in the play store (released 12th November). They will produce a new agent but will probably take weeks before updated in play store.
Workaround until then is to install older agent to enrol the devices using following steps.
- On first screen where it says “Let’s Go” tap anywhere on the screen multiple times until the camera comes up.
- Snap the attached QR code (it contains instructions to install old agent).
- Continue install as normal.
When they update the agent in the play store revert to the usual setup process.
