Immediately upon update I was booked and asked to sign in again, the interface is entirely backwards and frustrating, and seems more interested in finding ways to suck money out of me than actually providing me a solid comic reading experience. I had a really good time with comixology for years and the recent update left such a bad taste in my mouth that I'd signed out an uninstalled the app. It's a real shame, but I'm going to have to go back to getting my comics in person.
