If the iPad is visible in Apple Business Manager but not under Manage in Hexnode, it has most likely been assigned for Automated Device Enrollment but has not completed enrollment yet.
Try the following:
- In Apple Business Manager, go to Devices.
- Select the iPad.
- Use Assign Device Management and confirm that the device is assigned to the correct Hexnode MDM server.
- In the Hexnode portal, go to Admin > Apple Business Manager > Automated Device Enrollment > Devices.
- Click Sync and search for the device.
- Once the device appears in the ADE device list, factory reset the iPad.
- On the iPad, choose Erase All Content and Settings, not Reset All Settings.
After the iPad restarts and goes through Setup Assistant, it should enroll into Hexnode automatically and then appear under the Manage tab.
