Screen Time restrictions not working or showing up in settings

My app uses the ScreenTime API to allow users to block other apps. For some users, the FamilyActivityPicker doesn't render any apps, and they aren't able to block anything.

When they go into Settings -> Screen Time, there is no section titled "Apps With Screen Time Access", and when they go into Settings -> <my app>, there is no toggle for Screen Time Restrictions - even though they enabled screen time access when setting up my app.

Has anyone else seen this issue and/or resolved it?
