Trouble with thumbnail covers on Kindle
I have books in epub format on my pc.
I'm using calibre to edit the cover image in the metadata options.
When sending epubs to kindle via calibre, it's forcing me to autoconvert to azw3. Another option is to convert to mobi before sending. It doesn't allow me to send them in epub format. I don't know if that has anything to do with my issue.
Regardess of format, the covers I added via calibre in the metadata options do not show up in the thumbnails in the library.
It's worth pointing out that the covers are showing just fine when my kindle in in sleep mode. So the covers are in the somewhere. They just don't show in the thumbnails. What can I do?
