Okay, so these are the instructions
- Select the book without UUID in Caliber
- Choose "Convert Books / Convert Separately".
- Select a different format than the one the book currently has and convert it
- Remove old book formatting
- Convert the book to old format (if desired)
- Delete the format you first converted it to
- Send the book back to your Kindle
I don't know what 'remove old book formatting' means. And 'Send the book back to your Kindle' would erase the notes etc that I'm trying to save on the original ebook file.
Anyone have any advice here?
