I don't know if it's a know issue or not but on Pixel 10, GrapheneOS keeps forgetting my lock screen settings, particularly the set lock screen "shortcuts" (flashlight and camera) and the "dynamic clock" settings (which I turned off).
It often comes back, every few days, by itself, to dynamic clock turned on and empty lock screen shortcuts.
The workaround I found is going to my settings and turned them on/off again to reset the sate, or change the shortcuts to something else and back to flashlight and camera for them to appear again.
I don't know if it changes anything but I using a profile (different than owner).
