My Amazon paperwhite updated its firmware about a week ago. Since then when I use amazon.com to send books to my paperwhite, the amazon books won't show up in calibre. If I email a book to my paperwhite from calibre, it will go through and show up on the paperwhite, and then that book will show up when i connect my device via usb to calibre. However any books I send from amazon's cloud storage will not show up when i connect my paperwhite via usb to calibre. I used to be able to see the amazon books that are on my paperwhite device and manage them just like any other books. So hence i can mark them as read and send them to other people. Was there some new drm introduced in the update that made it so calibre can't see amazon books now?
