I have a flashcard app that had over 400 questions on it. They released an update that sounded great, but it wiped out all of my flashcards. I see the old versions in iTunes but I cannot figure out how to get it onto my iPad. I deleted the updated version so it didn't overwrite the the old version in iTunes when synching, but I cannot figure out how to get the old one back on my iPad. Alternatively if there is a way to restore from a prior state that will work. The latest iCloud backup happened after the app was updated.
Any help would be greatly appreciated. I have a huge test in a week and all of my notes are gone. The app is ISRS.
Thanks in advance-
