Fix the Restore Purchases... – Animal Sounds - Fun Toddler Game Review

For the love of God! I have uninstalled and reinstalled this app no less than 30 times when for no reason whatsoever the purchased cards "lock up" again and I have to try to purchase again and the app locks up. Fix this PLEASE for the sake of my sanity. :(
