App

No idea about that.

I suggest that you contact Amazon Kindle app support/developer team, explain your problem and ask for help.

You can use these instructions:--> How to contact an app developer - Apple Support

From what I can tell based on the threads on this forum, there's currently something wrong with the Kindle app for iPad. Until Amazon fixes it, there's probably not much you can do. However, you might want to reach out to Amazon directly for further assistance.
