Today I tried to access my PFD's in the iBook library but received a message stating I had to be connected to the internet. I had previously been able to access and read the entire library inventory while offline. Any idea what has happened? The message: "Couldn't Connect Apple Books couldn't connect to iCloud. Check your internet connection, then try again." Recently I was pestered to download and install an update. After downloading and installing the most recent kept insisting I enter my password for iCloud, this was not ever necessary before. I also had trouble with iCloud not showing files uploaded and visible with my computer yet they did not appear for over an hour on my iPad. I have two. One at least showed the new but empty folder. The other did not even show the folder.
