Hey, I looked at this thread
https://www.mobileread.com/forums/sh...ad.php?t=94772 and my issue seems to be similar that when I use Calibres edit book and add updated versions of the book and send it to the device. In this case I still get to see my old ToC but the new book has updated with the contents. This messes up ToC as I heard it was only generated while the book was being imported. Is there any way to update this metadata?
