App has been abandoned

The app wont recognize that Ive purchased the subscription in iTunes. The app also crashes a lot.

UPDATE: After selecting Restore Purchases several times, deleting and reinstalling the app a couple times, and after a couple calls to Sky & Telescope, Ive come to the following conclusions:

1. The app doesnt work properly when you subscribe through iTunes. S&T kept strongly suggesting that I subscribe through the publisher because they dont see issues when subscribed through the publisher, but they do when subscribed through iTunes.

2. The app hasnt been updated in almost 2 years. In this day and age, that pretty much means the app has been abandoned. Its no wonder that there are issues with it.

Ive switched to Astronomy Magazine. S&T is a great magazine, but if you cant access issues then whats the use.
