Hello,
So I use iBooks on my iPad (iBooks 4.8, but can't update), my iPhone (iBooks 4.9; iOS beta) and my MacBook Retina (iBooks 1.5). I am able to sync Collections across all three devices. Bookmarks on the other hand are not able to sync to my iPad. On Mac and iPhone they do sync. I do have enabled sync in the settings and I even tried different Apple IDs which came to the exact same result.
Anyone an idea?
Greetings
