Codes won't work – Tech4Kids Storytime Theater App Review

The app worked just fine until the last update. Now I can't get the app to work on one of our iPads. It keeps kicking me out of the app. I tried another iPad and the app works but I can't get the codes to enter. I purchased all the stories and had previously entered them. The last update wiped then all out. I tired entering the codes in and I get a message saying cannot recognize codes. The only way I can get anything to work is by using the press in play option. My child went from being able to work this by herself to needing help since it takes several steps to get the story to play. I wouldn't recommend this product. I spend all this money on it and now it's useless.
