I'd like to know if there is any way for an app to deep link the user to their Apple Account --> Personal Information --> Age Range for Apps screen within settings.
I don't have a feedback for this (yet). The idea is simple. If a user denies sharing permission, but the app developer makes the decision to use the API to enforce their own apps terms (i.e. 16+, 18+, etc.) one would throw up a non-dismissible screen and the user is stuck. The best I have come up with is to link to Apple's support page on the Age Range for Apps feature.
However, this isn't an ideal user experience and leaves a lot for the user to do. If they really want to use they can change their mind and I want to help reduce that friction.
Why does this matter? From my 'non-legal' research and experimentation with this API, I have decided the easiest thing is to just check the age in all regions--use it for checking and evaluating against your apps terms of use.
For example, I have a brewery app, while it won't check 21+ through the API, certainly the app is not meant to be used by minors. Aside from a few rough edges in the API, the framework is overall really well thought out.
Most people I talk with about this haven't even heard of the new Apple Account setting, and the ones that think they can find it go to privacy and security in the Settings app.
