My app provides VPN feature with packet tunnel provider. When I turn VPN ON, and app have new versions on app store, I can not update it. I can update the app only when I turn VPN OFF. When this problem happens, from the update progress bar, I can see it is downloading, but will stop at nearly complete.
Is it a limitation?
The behavior I observe is the following: the update is successfully downloaded, but only installed once the extension is no longer active. Fortunately, this also happens after coming back from sleep. As a result, apps will eventually upgrade itself, albeit not on the very moment where a user hits the upgrade button in the app store. I would not call this a bug per se.
