After a clean install of macOS Catalina, the device does not recognise that it is remotely managed. Instead after connecting to wifi (corporate or hotspot) it takes you to the usual setup steps for a brand new device, Transfer data, created local account etc...
I checked the status of the device in DEP assignments, it was still marked as "Assigned"
I then deleted the computer record from JAMF, no change on device however the DEP assignments table now reports "Unassigned"
Logged into Apple Business Manager and assigned device to JAMF MDM, no affect on device.
The device is essentially a new device and has no connection to our MDM, this is concerning because if the device was stolen we would have no way to track or manage the device and the thief could set the device up as their own. Even though the serial number is assigned to our MDM in Apple Business Manager and it appears as "Unassigned" in the prestage enrolments.
