For me at least its perhaps confusion with the fact that we are talking about sliders , in under the “App and Site Blocking” menu… so is a slider in the ‘on’ position doing an App Block or App Allow? maybe the menu option should have been “Allowed App and Sites” or “App and Sites overrides” …
Yes, therefore, Steam was enabled for “Kids” as was Minecraft Online , (also re the sliders, why can I have both those sliders ‘on’ yet the ‘Gaming’ slider in off? (and visa-versa) … I do have all 3 on the ‘on/right’ setting, but again its a little counterintuitive as to what it would mean if gaming is on yet both the sub choices are off… or other way around… gaming off yet one or both sub-choices are on…)
The only other Category I have enabled for ‘kids’ @ present is “Search Engines” and the “Google SafeSearch” listed within.
