I am using GOS with a 3 user configuration. Owner installs all apps and disables 95% of them, Daily user has no google apps. My "invasive" user is mostly google play store apps.
If apps are installed and disabled, will they get regular play store updates even if I don't use them in the google user?

    Yes, even disabled apps in the owner profile are updated in the other profiles. There is only one app version installed.
