My iPad just informed me that there's an update for BTTF part 1.
BUT. The description says that if I update part 1 and want to delete parts 2-5 from my iPad (I've finished the game) and free space, I can never again re-install them without paying you again.
I mean, WTF? You can check which AppleID has been used to purchase the parts, it shouldn't be a problem allowing those who have bought all parts to be abel to download the episodes with the new app.
So, fix this. We've paid for the episodes, we want the abality to choose when and where to install them. What you're proposing now is extorsion: "Do as we say, or you'll pay". That's no way to treat customers.
