karlachameleon Will updating an app in owner profile update the app in the other profile(s) it's installed in without action in it(them)?
Yes.
karlachameleon You can update the app in owner profile if it is disabled rather than just not used?
Yes, that is my understanding, but I have not verified it personally. In theory an app store could decide not to automatically update disabled apps, but it seems unlikely that any of them would be checking for this, since AOSP doesn't even allow user-installed apps to be disabled.
