I have downloaded a game on my iPad (hopefully free), played for a while. Then, after several days, the app crashed. The current situation is that this app starts, but during initial loading, it crashes. I've deleted the app and then re-downloaded it from the App Store, believing that the corrupted file had been deleted too. But the problem stays the same: crash at startup.
So my question is: when I delete an app, does it leave some files on the system? And if it is the case, is it possible to get totally rid of an app?
