I like the service, but the app has serious problems that appear to be caused by a recent update. Comics wont load, or will partly load, or only 3 pages will load and the app thinks its literally a 3-page comic. The only solution is to quit the app and re-launch. If you want to do some binge reading, you can expect this to happen numerous times.
