We manage our enterprise app's runtime updates by means of...
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-services://?action=download-manifest&url=https://xxx.plist"]];
This has always worked well. When called, an alert is presented asking for permission to install, the app closes, and installs. Suddenly, this stoppped working for all our apps. Running on iOS 8 and 9 (not sure how that is possible). Now the user is prompted for the install, but the app never closes and never completes the install.
Only if the app is manually closed (Home button) will the install complete, and even then the app's icon remains on "Loading" for about a minute (with a partial radar icon) and the install eventually completes. If the user never closes the app the install never completes.
Is anyone else experiencing this sudden change?
