Has anyone experience device enrollment and work account sign in issues since Apple has updated and change their Apple Business model. I am a IT technician at a MSP and up to this point before the change I was able to enroll devices without using the Apple Configurator and simply signing into my client work account in the device general tab under vpn.
This would allow the preconfigured app assigned to populate. After the update I tried to sign into the client work account, and I was receiving a signed in failed error. Now according to Apple Support I have to use the apple configurator, and it took a while for the device to show in Apple Business and now it seems that every work account, I try to sign in with including my administrator account, I use I receive a verification failed error.
