I absolutely love audio books and the immense library that the service is offering. But the app is a messy mixture of website store/app. I have problems with app's handling of my credit cards (this happens only with audible!) The problem exists for more then 6 months now. Can't delete my card, can't add a card and the only payment option are credit cards in the fr store. Where my whole library resides. Support promised a solution, nothing happened. My email remains unanswered.
