I just wanted to mention that since the last couple or so updates, it seemed like the ability to access any of the app settings went away since the app would prompt the user to either make the purchase or restore their purchase. Tapping on the restore option gave me the error stating that no previous purchase was found. This was the case in the App Store version as well as the beta version. I ended up purchasing again to allow me to access the settings.
Thought I'd mention this since it seems that the record of the purchase that we made previously, was not picked up via the restore option.
