Our main trouble is that there are like 30 Web- or streaming-capable devices in our house, not even counting ones that are packed away, and getting the balance between "usable by adults with little friction; locked down for kids" right on all of them is a real pain. Only the Apple-ecosystem stuff is relatively easy to manage, as far as that goes.

Worse, some of them are school devices that we can't manage. And having to physically manage device access is another annoying, never-ending task.
