The earliest recollection of this bug is traced back to PAN-OS 9.1.6 - July 29, 2024. This bug is fixed in PAN-OS versions 9.1.6. Fixed an issue where a passive Panorama appliance reported that device groups were out of sync despite a successful HA sync from the active Panorama appliance. This issue occurred when the address objects defined in the device group were in use under the corresponding template.
