Now broken in iOS7 – Fine Homebuilding Magazine Review

The latest updates seem to have broken the app for users still in iOS7. The app now tells me my subscription does not exist and that I have never purchased any issues. This seems to happen every time there is an update of the app or iOS. It is amazingly frustrating to plow through all the seemingly related FAQ, following the supposed fixes to find that nothing works. I have wasted so much time on trying to fix this problem and to no avail.
