A while ago I downloaded E. O. Wilson's Life on Earth from the iBook Store. Produced by iBooks Author, it is being progressively updated with new chapters. Over the last few weeks I keep being notified that new updates are waiting for this book, but in each case it is the same update being brought to my attention.
Even though I have downloaded and updated the book with these four additional chapters at least four times, it loses the new chapters and therefore prompts to be updated again. Without being absolutely certain, it could be that the notification for updates occurs after I have synced my iPad to iTunes again.
Has anyone any suggestions about how to recitfiy this problem and how do I let Apple know if there is a bug?
