        I'm observing problems upgrading apps with an active packet tunnel provider on iOS 11. This issue was previously reported as a bug and believed to be solved in iOS 10.2. Unfortunately I have to report that this issue is back on iOS 11 and based on the tests it seems to be 100% reproducible.

         

        Steps to reproduce:

        1. Install Ad Hoc / TestFlight version of app

        2. Enable tunnel provider

        3. Update to new version of app (App store version, Testflight or OTA)

        4. Find that the update fails, a dialog is shown that the download failed     

         

        Previously (after the fix deployed on 10.2), I would see the VPN icon go away shortly before the download starts. Now, on iOS 11 beta 3, I see that the VPN icon remains visible and the extension is not closed before attempting to download a new version. The console logs specify the following:

         

        Jul 17 13:55:52 <devicename> SpringBoard(FrontBoard)[53] <Notice>: Error acquiring hold on plugins for <your.app.bundleID>: Error Domain=PlugInKit Code=14 "plug-ins are busy" UserInfo={busyPlugInUUIDs=(
                {
                XPCExtensionBundleIdentifier = "<your.tunnelprovider.bundleID>";
            }
        ), NSLocalizedDescription=plug-ins are busy}
        

         

        This bug is observed for our own apps, internal test apps as well as a handful of app store apps using packet tunnel providers. It has been reproduced on iPhone 5s, iPhone 7 and iPhone 6 plus.
