App with DeviceActivityReport extension either won't install on device or won't upload to TestFlight

We have integrated DeviceActivityReport to our Family Controll app. All capabilities are added. We built the app and tested it, but when we want to upload to TestFlight the following error happened (see attached image)

When we are adding NSExtensionMainStoryboard or NSExtensionPrincipalClass the following error appears during installation process.

DeviceReport.appex with id com.example.example.DeviceReport defines either an NSExtensionMainStoryboard or NSExtensionPrincipalClass key, which is not allowed for the extension point com.apple.deviceactivityui.report-extension

Same issue here, we get this after submitting the family-controls-distribution for both the main app's bundleID AND the bundleId for the DeviceActivityReport extension.

This seems like a bug from Apple, and it totally prevents anyone from shipping an app with DeviceActivityReport extension.

Can anyone from Apple weigh in???
