Great Mag - multiple problems with missing issues

The mag is great and the App is great when it works but unfortunately, I have had to restore me purchases several times and most of the time it doesnt work as described. For example, with this last iOS 9 release, once again it lost my subscription and all issues need to be restored individually. Unfortunately, and inexplicably, only the mid portion of my subscription is available for restoration - the first several issues (I was a charter subscriber) are not restoring and show the "Buy" label instead as to the most recent several issues.
