When supervising a device, I try to install a profile contains the payload type :com.apple.webcontent-filter. The OS displays that: the payload type "com.apple.webcontent-filter" is not permitted. I'm not sure which step went wrong.

How can I know the APNs notificaiton is sent to device(success/receive time)? In my notification server, it only get the result of sending a notification to APNs, not from the APNs to device.
