Tested on iOS 15 Beta 6. shield can be activated/removed from within the main app. DeviceActivity Monitor extension called properly but did not apply shield. Beta 6 comes with more bugs than Beta 4. Application picker UI is totally messed-up

Child applications are visible on parents device on iOS 15 beta 6

child apps are now listed on the parent device if both phones are in iOS 15 Beta 6
