gosrox Its a bug. Works for main profile but not secondary. Should be fixed for secondary profile or setting hidden if it cannot have required permission.
I'm not sure I follow this comment. Are you suggesting that the GrapheneOS team should either hide the setting or fix the bug?
Although I haven't actually checked, this kind of feature being broken is almost always an upstream bug, so it should be fixed by Google. GrapheneOS devs probably don't have time to fix it, so unless someone else in the community does, we will have to wait for Google to do so.
