Blank pages in downloaded books. Books aren't easy to find. Issue 1 can be next to the series "group" instead of actually in it. Search doesn't work if you want to search for a book title (only the series with the searched word show up). Searching on is awful (searching for 'Doctor Aphra' brings up nothing but search for 'Aphra' and voila!). There's no preview pages. Almost as bad as the kindle app. Should've just given the option to read comics on kindle instead of changing the app entirely.
