- Yes, when it's set, you can install apps within that specific profile.
- They will be shown in the owner's app list in settings as 'not installed for this user' (this user meant owner) unless you install they directly in owner too. But they just appear in owner that way, not in other profiles.
- Yes, if an app is disabled in owner profile (or in any other profile or in all profiles at the same time) this app will be updated as usual.
You can also install an app in owner profile and push it to any other secondary profile, but you may still know that. Unfortunately you cannot do this vice versa, install in a secondary profile and push to owner or any other profile, (see 2) maybe for security concerns.
