Hi,
Thank you for posting in Microsoft Q&A forum.
Here are some steps you can take to troubleshoot and potentially resolve the issue:
1,Please confirm that the devices in question are in compliance with your organization's policies. If a device is not compliant, it might prevent automatic updates.
2,Also make sure the devices have an active internet connection. Automatic updates require an internet connection to download and install updates.
3,You can try forcing a sync between the Endpoint Manager and the devices to see if this triggers the updates.
4,Are the problematic devices and normal devices in the same group? Do they get the same policies?
Thanks for your time. Have a nice day!
Best regards,
Simon
