What I am trying to do:
I have two users setup in the tablet. First one is admin(account1) and the second one is regular user (account2, not a guest).
Tablet requires me to install all desired applications to both accounts seperately. For the admin account (account1) everything worsk as it should. MicroG installs fine and then Vanced, no problems all golden.
When I try to install microG from the Vanced Manager, to the account2, I get the error in the screenshots.
I can read, so the issue is with permissions for the user, but I have absolutely no idea, how to fix this or work around it.
How do I give permission INTERACT_ACROSS_USERS for the app or for the user?
