Me and my kids' mother aren't tech savvy.
We purchased some sort of Disney filter/security thing. Kids got on reddit and figured out how to bypass it. We purchased another one (don't remember the name) and kids were able to figure out how to bypass it too.
We couldn't figure out how to get the Apple security features to work half the time either.
Every parent we knew was having the same struggle.
We lost the battle and are losing again with my youngest.
