Your customer is provisioning devices via zero-touch enrollment deploying multiple configurations. They report that a group of devices is not enrolling automatically into their EMM, while other devices have enrolled successfully. You have already confirmed that the devices are listed in the zero-touch console. The end-user reports seeing an EMM-branded screen on the device, but is unable to login. What would be the next troubleshooting step you would advise?

The correct answer is to check that the DPC extras are correct according to the EMM. Since the user sees an EMM-branded screen, it confirms the zero-touch enrollment successfully directed the device to the EMM's Device Policy Controller (DPC). The inability to log in suggests an issue with the information passed to the DPC, which is handled by DPC extras in the zero-touch configuration. Incorrect or missing DPC extras can prevent proper EMM enrollment or user authentication. Re-uploading devices is unnecessary as they are already listed and reaching the EMM screen. Removing domain binding or re-adding Managed Google Play binding are broader EMM integration steps that would affect all devices, not just a specific group experiencing login issues after reaching the EMM screen.
