In my Android Kindle app, after opening my book and then going back to the library, the cover thumbnail isn't shown at the bottom center of the screen. However, after doing the same thing with my friend's book, her cover thumbnail is shown. (See the attached image.)
Both books were side-loaded, and my intention is that my book will always be side-loaded.
My epub was generated by Atticus. My friend's was generated by Vellum.
I compared the epubs and tried some things, including:
- Adding the cover-image property to the cover element in my content.opf file (it had been missing)
- Removed the '<meta name="cover" content="image_cover" />' element from my content.opf file (because Vellum's epub didn't have it)
Neither change fixed my issue.
Any ideas?
