I've used this app for years and loved the experience. However, with update 4.0, I can no longer recommend this app. It's nothing but a glorified eReader now (since I live outside the US). Almost every feature is gone. I can no longer search for new comics. I can no longer buy new comics. There is no details page for info on creators/series. The Amazon website doesn't advise if I already have a title in my library. Consolidate the store but give the features back Comixology.
