@adr, Thanks for posting in Q&A. From your description, it seems we have two policies. One is configured UpdateCompliance settings. And one is configured a workbook for WUfB with our subscription and Workspace. The second policy only apply to a small group but it affects all the devices in the environment. If there's any misunderstanding, feel free to let us know.
From the above description, the phenomenon is a little strange. To clarify the issue, please collect the following information:
- Could you check if any other policy with the workbook configured assigned to these affected devices?
- Please get screen shots of the policies' properties we configured.
- For the WUFB policy, please let us know how the assignment is configured. And can we see the device status under the report of the policy which we are not assign.
Please collect the above information and if there's any update, feel free to let us know.
