I have an iMac that was in Apple School Manager. I meant to temporarily unassign it for troubleshooting purposes, but I think I must have released the device instead because now I am not able to add the serial number back into ASM. Apple Support told me that I'm basically out of luck and I can never add that computer back into our DEP ever again. They told me that it is essentially released forever.
I can't believe that even Apple cannot help me re-assign this device, even with proof of ownership. Has this happened to anyone else? And if so, were you ever able to re-assign the device in ASM somehow?
