Hello，is the problem solved now? How can parents APP block the applications on the child's device

We are working on a project of Parent Control. There are two applications one for parents and another for children.Parents application can block applications on the child's device. I call 'requestAuthorization(for: .child)' on the child App. Do I still need call it on the parent App?

There was the same situation when i call requestAuthorization(for: .child). And it not displays the authentication sheet when my app first launches call this method. But when i change the argument "child" to "individual" and call the method there displays the authentication sheet. Does anyone know why this is happening? Thanks for your answer.

Looking forward ! I asked Apple DTS for this demo, but they replied they didn't have the code.

Looking forward!
