Update Profile over cellular roaming
Just to close the loop on this, it seems that some of the profile changes made were stopping the update from happening. I think the particular issues were swapping between normal lockdown and activity suppression lockdown. Reverting to a previous version of the profile was possible and then I was able to revoke the profiles.
It just turned out the phone this first occurred on was roaming at the time. After a bit of testing it also started happening with devices on WiFi.
In that case, you probably have to check the deployment server/Desployment-Server Extension log files for any clue from warning/error messages. You might have to set the log-level of both to verbose to see more details.
Thanks Raymond, I had not noticed that tab. Unfortunately, all of the options are already ticked.
You can check various network-restriction options in the rightmost "Options" tab when assigning an Android profile, and "Romaing Resrictions" configurations in Advanced Configurations associated with the device/device-group for iOS devices.
