Hello! I am working on a screentime app and wondering if anyone has had success achieving reliable background shield application while using com.apple.ManagedSettingsUI.shield-configuration-service?

I recently switched from com.apple.deviceactivity.shield-configuration (which worked reliably but isn't accepted by TestFlight) and have not found any consistency getting shields to apply while the app is backgrounded.

I believe this is a known limitation of ManagedSettingsUI and want to know if there are successful workarounds or any specific patterns/timing that improve consistency?

Hi there! I am having a similar problem too. I use DeviceActivityMonitor to set 15 minute sessions for removing apps' shield. After 15-minute session is done, shield doesn't apply reliably in my internal testers. It applies if the tester is in my app or in blocked app but it doesn't if user's phone is locked or they are using another app.

Although in my device it applies successfully when I build it from Xcode. This made me think whether this is a provisioning/build issue or a reliability issue (of device activity extension).
