Revising my original 5 star rating down to one. This app is no longer usable. The web site is even worse. For years, I've been buying my books and using smart lists to govern what I download. Now I have to go to the web site and search all over the place for my most recent order so I can download in the app. This has to be the worst change I've EVER seen in an app. I can't even ask a question at the web site as they're fully Amazon and not contactable. Lost a customer, guys!
