This app works okay, but the problem is the handling of unread, favorite, and updated manga. Its a pretty simple, and straightforward requirement. I just want to know when my favorite manga have been updated so I can read the latest chapters. Unfortunately, filtering with “Unread“ gives you manga you've never read, and filtering on “Updated“ seems to give you a list of recently updated manga, but there are still manga missing from the list that have new chapters. It's practically worthless. Other than that, the rest of the app is great, but the filtering funtionality is crucial to make this app actually useful. Please fix this!
