Been so frustrated by the plethora of controls, their various inability to do what I want and the constant need to check the settings to make sure they didn't fail open or that I just forgot to lock something back down because my children needed access to do school and I was in a hurry and just disabled everything because it was simpler.

Adding multiple devices of different types just exacerbates the problem and made me set everything to max lockdown and only unlock on demand.

We have a switch. You can't lock it. You can set a minimum playtime of 15 minutes but then the kids sneak up to the attic and get their "free" 15 minutes of playtime in the middle of a school day. You can't set playtimes individually per kids account either.

We have a family imac and our teens have android phones so now I've got three separate family account managers to use, family link (Google), screen time (apple) and Nintendo. No, make that 4, because I also have ubiquiti networking and have a separate WiFi network for kids devices so I can block the school provided chromebooks which I otherwise have no control over.

You know what we've resorted to? Keeping devices in our bedroom and physically controlling them. Super simple, no passwords or random fail states.
