Hi everyone. I use Apple Books a lot, both on my iPhone and my Mac . I use iCloud to sync my books, bookmarks, highlights, reading progress, etc. across these devices. In the past, it worked. However, I the last few days I upgraded from macOS 10.14.1 to 10.14.4 and bought a used iMac. The first thing I did with the new iMac was to erase the hard drive and perform a clean installation of 10.14.4. When I opened Books for the first time on the "new" iMac, all my books were listed, but only a few of them had the cloud symbol on the top right to indicate that I can download it from iCloud. When I double-clicked on these books, they were downloaded and I could open them. However, when I double-clicked those books that did not have the cloud symbol, nothing happened. They did not open or download. I then created a new user on the iMac to test how Books behaved there. To my surprise, the collections were not organised as they were before and the imported PDFs were all missing. What I also find suspicious is the fact that the iCloud storage statistics (Settings -> Apple ID -> iCloud -> Manage Storage) on iOS show TWO entries for Apple Books instead of one (see attached screenshot). One of these two entries shows all the PDFs I imported into Books, the other entry shows no details at all. Moreover, the statistics view states stat I use only 1.7 MB of the iCloud storage - despite the fact the two entries for Apple Books together amount to almost 40 MB. I restarted Books several times, signed out and back in again, restarted the iMac, etc. but all without success. All help is much appreciated!
