I have taken over managing an older enterprise app that is deployed to target iOS 5.0. We are having random problems with the app after recompiling changes to the content data. The problems seem to only effect 64bit iPads. There are random failures to overwrite existing data. The most obvious being changes to the URL Scheme in xCode is not being reflected in the app. The result is that when the new enterprise app version is deployed some of the new info doesn't seem to be getting replaced for all iPads all the time. Hence calls to a given URL scheme are failing to open that app on some pads and not others.There are other details that I have sussed out but those are the big points. Any comments would be most welcome.
