On my iPad, I have routinely exported files in Dropbox to Books (iBooks) to read offline. In iOS 13.3, Books is no longer an export option. The only option I see is to open in Acrobat. How can I export to Books?
Thanks, Daphne! You solved it. I updated the Dropbox app and, presto, all of my Export --> More options reappeared. I think the problem was a disconnect between the newest iOS and an older version of Dropbox.
