How do you delete issues after reading?
Under the downloaded tab of my DC you can click the three dots under the issue and remove download should be there
How do I download a book
This is only possible on the mobile app (available on iOS and Android!).
Select the comic you wish to download → click the ‘download’ button. It’s located under the ‘READ’ button on the right hand side and features a downwards arrow pointing at a horizontal line.
Hope this helps!
