Some users have mentioned they are having trouble restoring in app purchases. I have submitted a new version to apple which should fix that problem – sorry for any temporary inconvenience this may have caused you!! It’s been an ongoing battle trying to streamline this in app purchase process. It’s very over complicated on the backend trying to get it all to function nicely. And, man, if someone tries to purchase the product and it turns out they haven’t put in their credit card information into their iTunes profile yet, so then they leave the app to go do that and then come back – forget about it. The whole process just implodes.
