Of all bungled things Apple ever made screen time is by far the most painful.
- Screen time synchronization from parent iPhone to child iPad works only erratically. Was worse 2 years ago but is still a mess. I stopped the synchronization between devices and do all screen time configuration directly on the child's iPad. To stop the "share between devices" I had also to log into my account on my wife's MacBook (which I normally never do but for some reason I created the account 4 years ago) to switch it of there manually as well.
- The screen time settings app look different on different devices even in the same OS.
- And if you really want to ruin everything: Give your child that only has a iPad an account on your MacBook. Then all the iPadOS-App show up in the settings on your MacBook and nothing works anymore. Really nothing. First I had to find a way to delete everything (was not easy, since many options in the settings had been greyed out), then I had to make sure that there is really no sharing between devices enabled on any of our devices. Only then I could create everything from scratch again.
My theory: Apple employs to many young, dynamic but childless people as developers who really have no clue about organizing a family.
I always thought it would be a good idea to target parents as customers so that kids get an Apple product right from the crib. But it seems as if Apple knows better .... :-(
