Is there a way to set a "bedtime" from parental controls that limits app function during certain hours? My son uses his 4 Pro for music and an alarm (which are easy to do with other electronics if needed), but he has friends that text late into the night. For now, he has just been muting the conversations each evening, but it seems a little cumbersome to do daily. It would be awesome to have a feature that sets "do not disturb" hours for things like calls/texts/notifications, but I am not finding that function.
