Hi Folks!
I use Calibre 3.40.1 with Win10 x64.
I searched in the forum and manual for a solution, but found none. :-(
https://manual.calibre-ebook.com/edi...adding-a-cover
https://www.mobileread.com/forums/sh...ighlight=cover
The issue is
a) Calibre 3.40.1 does not import the cover of _some_ epubs, even though the covers are embedded (as cover.jpg in the epub itself)
b) If I add the cover via "Edit"-"Add A Cover"->'Save' and restart, I still can't see it in the library.
BUT: If I import the epub a second time, calibre's library shows the book cover in the second instance of the book.
Thanks for reading this!

Maybe you have an idea!
Andy
I tested the 'repair ebooks' function in 'edit ebook' but it did not help.
