Like many other reviews I too had problems when I try to back up to iCloud. I contacted the help line via the link within the app. I was contacted right away and was told that they would help me recover my lost stories. They have since launched a new app, Disney story central. They also gave me a code to use all of my tokens on new books within this app. While this current app may have bugs the new one is great and Disney is fantastic with their customer support!
