Re-awakening this older thread... I have three phones on GrapheneOS- two Pixel 6 and one Pixel 7 for my little daughter. Trying to block youtube shorts using OpenDNS on my home network. To do this: 1) set up OpenDNS account and register IP of router 2) At OpenDNS config page, select "block video sharing sites" 3) ensure phone is in fact using router wifi not mobile data.
WEIRD THING IS on my phone (Pixel 6) this works. Cannot reach any youtube site. But on her phone (Pixel 7) it blythely connects to youtube as usual. WTF?
Another thing. On my phone if you set "use mobile data" to OFF, it stays OFF. You have no internet when out and about. On her phone (Pixel 7) mobile data mysteriously re-enables itself. This happens even when in addition I set a mobile data limit- it gives nag alerts but re-enables or continues to use mobile data. It is not the child changing settings because I have Timelimit installed and she cannot access Settings.
Any assistance here? Thanks a lot!
