Can’t restore purchase – MP3 Audiobook Player Review

I liked this app, so I decided to pay the $2.99 to remove the ads and the limited duration. After getting a new phone, I’m not able to restore my purchase. I don’t get any error message or anything. It just won’t do it, period. I wish I had purchased the pro version instead of doing the in app purchase.
