Unable to access my In-Purchase

Im thinking this app and the in-app purchase still needs a bit of tweaking. I have bought the in-app purchase to access "Johns Notes" but when I try to access it on another device, I cant Restore My Purchase because it keeps telling me I need to be signed in with my account. I have been signed in. I have done everything according to the instructions, and I still get access it. :-(

The overall bible part is just "ok" too. Sadly after spending a little bit of money for something I cant use, I will have to remove this app and just use my Olive Tree one.
