[HELP] "Action required for browser protections" alert

The warning most likely appeared because the scoping changes forced Purview to rebuild and republish the browser-protection policy. Repeatedly clicking Resync will not make propagation immediate, and the banner can remain for up to 24 hours after the last policy change.

Stop making further changes for now and review each affected DLP policy. Confirm that it is enabled, the Devices location is active, and the same device group is not included and excluded through different scopes. Have a Purview Compliance Administrator perform one resync, then allow a full 24 hours from the last edit.

On one targeted device, confirm that it is still listed as onboarded and active in Purview, update Edge, and use an Edge for Business profile signed in with the organization account. Open edge://management to confirm that Edge is managed and edge://policy to reload browser policies. If the device is Intune-managed, also run a work-account sync from Settings > Accounts > Access work or school.
