Note: All the devices/accounts mentioned below are part of the same Family Group/ Is it necessary for the "parent-side" application (that uses FamilyActivityPicker to select the list of restricted apps) to be the same as the "child-side" application (that will request FamilyControls permission and will implement the DeviceActivityMonitor extension), for FamilyActivityPicker to work as expected? My observation is that given the FamilyControls permission being granted on the child device, FamilyActivityPicker when used on the parent device and rendered on an app with a different bundle identifier works as expected (by populating all the apps installed on the child device) in case of iOS 16 and 17, but does not work for iOS 15 (I am testing on iOS 15.8).

I am trying to develop an application that can enforce Screen Time restrictions on the target device, however I get stuck at the part where I have scheduled callbacks for my class that implements the extension for DeviceActivityMonitor. For debugging, I first attach to the app extension target process via Debug > Attach to Process > Process Name. But after scheduling monitoring that receives a callback immediately, the process exits with the following error: Thread 1: EXC_RESOURCE (RESOURCE_TYPE_MEMORY: high watermark memory limit exceeded) (limit=6 MB) Is the maximum allowed memory for Device Activity Monitor extensions really just 6 MB, or am I doing something wrong? If it is indeed the case, is there any way to increase it? 6 MB seems quite restrictive to me.
