Stopped working and lost the decks I paid for – WH Question Cards: Who, What, When, Where, Why Review

What happened? This used to work so well. My son showed me that the app kept freezing after choosing the deck and player, so I deleted it and reinstalled it. Now the decks that I purchased have disappeared, and the app still isn’t working with the one remaining deck. I purchased this because you have been a reputable company in the past. Please fix these issues.
