We’re not sure if it was a bug or a loophole in the iTunes App Store, but in the past, when an app was refunded and the user got their money back, they were still allowed to reinstall the app at a later time and even update it. Essentially this meant that you could technically buy a paid app, download it, install it, and ask for a refund, but continue to use it later anyway. Well it looks like Apple has decided to shut that door for good, although it does seem like Apple did take their time going about it.
