I have a Pixel tablet and phone (6a) running GrapheneOS. The tablet shows a button at the top right of the screen to switch between user profiles but when using the phone I am using Settings/System/Multiple Users/(select profile)/Switch to (profile).

Is there a shortcut to switching user profiles on my phone or one that I can add to my home screen?

    Swipe down control center completely, then on the bottom of your screen on the right edge u have power icon, to the left settings icon and one more to the left users.

    MotherShipton Swipe down twice, and the shortcut is there at the bottom of the screen.
