That's what I meant by the technical term "dosn't work". Rendering in the wrong place, mad flickering making the app useless to the user.
Shinobi have confirmed that the version we used v2.2.1 does not work on 64 bit hardware even though it does work in the 64 bit simulator. Affected apps need to use one of the patched versions, or the latest version (v2.5.5). In my case, linking the app with v2.2.1a did the trick. Now I have to wait for Apple to approve the new version while my users continue to download broken software.

In other words, it won't be fixed until you rebuild your app using a suitable version of ShinobiCharts and submit that new build to the App Store.
