Ever since the forced update Merging Comixology and Kindle the app has turn to trash. My books are organized in random fashion with series not being grouped together. Some of the book I've purchased still aren't showing up. Also I can no longer add books to my cart and pay for them all at once. Now I MUST use 1 -click buying which I hate and am not able to turn it off. Hopefully someone else comes on the market cause this once great app is now GARBAGE.
