No! If edits were made to the board, simply refresh your book design page and you should see the updates to the book content.
Alternatively, if new posts were added to the board, after refreshing the book design page, a pop-up will appear that asks if you'd like to include the new posts to your book.
Please note that any edits made to your book layout after a book order has been placed will not be reflected in your book order, as the file that submitted to our printing partners at Blurb when the order is placed begins printing almost immediately.
