Responding to an alert- 2 parts

Hello,

I received the attached alert.  One, I cannot find on my son's device what it suggests I do:

"To ensure that time supervision and app supervision are turned on, select Norton Family in the Access Application Usage Data screen on the monitored device. This screen can be found at Settings -> Security -> Apps with Usage Access/Access application usage data (under Advanced)."

(He has a samsong tablet sm-t350 with a 6.0.1 operating system)

Two, is this something easily undone by him or not (do i need to make sure he's not a system admin or something

Thank you!  -Carl
