Lost two hours of my work – Tinycards - Fun Flashcards Review

I spent two hours updating my deck at the library. I clicked Update many times. However after I logged on at home both on my computer and the app, all of my additions were gone. I know it’s the same account because the deck is still there... just missing about 100 cards. Thanks for nothing tinycards!
