What have you done to this once functional app?? This latest version when searching for books all black screens, very little information, if it is a series, you can't search the series, if you search by author you have to go through a small dark list that gives you no information. If you set up a search and click on a book to look closer, when you go back, you have to start all over again. Other apps and services are doing it better. If I could give negative stars I would. You lost me
