Until now, using the Comixology app has been nearly a flawless experience. I'm in Canada. I now have to go to the Amazon app to buy comics. There, all superhero titles are lumped together and hard to filter and sort. Switching between two different apps makes no logical sense. The new Comixology app is buggy too. After a search, I couldn't get back to my Library, and I've had titles suddenly switch back to the first page. Most of all I miss the sales! Overall, this is the biggest app fail ever!
