Reregistering Jamf Remote Assist removes the Privacy Preferences Policy Control profile that was deployed to the computer when Jamf Remote Assist was initially enabled. Then, the Privacy Preferences Policy Control profile is immediately redeployed to the computer and the computer goes through new authentication to ensure that future communication with Jamf Remote Assist is secure.
After reregistering Jamf Remote Assist, try initiating a Jamf Remote Assist session again. For more information, see Starting a Jamf Remote Assist Session.
