I'm starting to investigate restricting access to the App Store on our macOS, iOS, and iPadOS devices. The technical side is easy enough with just a config profile, but I'm unsure what will happen to existing machines that have installed things from the App Store. I don't think these applications will be uninstalled, but I'm not sure about if they'll get future updates.
Can someone clarify the behavior around existing App Store installs after the App Store has been restricted?
