Frustration

I downloaded the free version to try for my 4 year old son and 3 year old grandson - who were VERY intrigued by the story - until it stopped and said "buy full version". Since they were so disappointed that it was over, I did what I swore I never would do and paid for an app. Your app. Yes, my very first app purchase and I will say, Im a BIT disappointed and heres why:
Now when we go to read the story, at the very spot where it asked us to "purchase now", it stops and tells us to "restore"; so we have to stop the fluency of our reading, click a button and wait... Then it takes us back to the main screen where we have to RESTART the story all over again not only frustrating me, but the boys even more so. I was going to try to download the main paid app, but Im not taking the chance and being charged twice - especially when I dont like to pay for apps in the first place. Please help me with this... This is our fifth time attempting to read it and it would be nice to be able to read what I have paid for, uninterrupted. Tonight was the first time they said, "forget it. Lets just read something else". If this happens and they give up on you, I can assure you I will, too and will avoid your company in the future.
