I canceled my Comixology subscription because of the recent app update, although the integration of the Comixology Web page into the Amazon store page was a near last straw. Now with this app update pages are missing from comics, downloads don't ever finish... Sounds like I'm one of the lucky ones who didn't lose their entire library or try to clear a cached comic with the "delete permanently" option and find out they just gave up their digital right to read the issue.
