Hello! I've been uploading books and mangas onto my kindle the past day or two and one thing I've noticed is that the covers will revert back to how they were originally when I viewed them in Calibre.
All my books are in EPUB format (haven't changed the covers on those, no need to as of now) and my mangas are in CBZ format, which are the ones that change. Is there a step or two I'm missing that I need to do in Calibre to ensure the covers stay?
