DeletedUser495 If you don't want to use background data, you might as well disable the app after the use since it won't be able to perform any meaningful (network dependent) activity.
DeletedUser471 DeletedUser495 ofc I keep most of apps disabled but few apps I need to be at hand with battery usage and background data restricted.
qnp I recently installed GrapheneOS and encountered the same bug: in secondary profiles, after rebooting the phone, the revoked "background data" permission is automatically restored for any apps. I can confirm that this issue is still present.
Novaliss qnp DeletedUser728 From testing a bit, the 'allow background data' reverts, but this far I haven't found any other settings that reverts themselves that way.
