I'm stuck with my son not able to play minecraft from his nintendo account anymore though it used to work. I'm just getting an unhelpful error message and all permissions should be enough. Parental control is a joke. Deezer has kids accounts but you can just switch to another account. Spotify kids was a joke when I used it, poor discoverability, poor cataloge specifically if you care about childrens audio books.

Google family link is also kinda weird. As a parent I don't want to restrict the time per app or total usage time. I want to limit usage of a group of apps. E.g. i don't want to limit spotify but I want to limit the total play time of certain games.

So I agree with the sentiment of the post. But maybe I should consider the route from my child hood: unrestricted access. At least I know, in contrast to my parents, what is out there.
