I try to go into screen time for my daughter and it won’t let me in to adjust anything. It freezes and I have to close out the settings app completely by swiping up. I’ve tried turning my phone off and doing a hard reset but it still does that. It worked completely fine until the most recent update.
These are the Developer Forums, where developers of apps for Apple's platforms ask each other for hints and tips on coding.
Your question is more of a product support one, so I'd suggest you ask it over at the Apple Support Forums. Thanks.
