Can't get a recently added ePub to synch to my iPad
I created a short book in Pages, exported it to ePub format, and successfully added it to my Books library. If I go into Books, I can see the new addition, open and read it.
However, after I do a synch with my iPad, the new book is -not- on the iPad. My synch settings are to synch everything in my library over to the iPad.
How do I get the new book to properly be added to my iPad?
