Latest Calibre, latest Kindle firmware (Jailbroken) on Paperwhite, MacOS
I noticed around Christmas (got some new books) that when connected, books that are 100% on the Kindle don't show up in the Device view.
Even when I've downloaded the file from amazon and have the book in my calibre library, it doesn't show as in memory, and searching on the device, gets zero results, even though I've read one of the new books already, and know the rest are there.
Figured I'd throw it out there in case anyone has seen and fixed it, or at least can validated I'm not alone
