You can edit your book anytime, but changes made after placing an order won’t update the book currently being printed. The printed version will always match what you approved at checkout.

If you want the updated version printed, you can place a new order, or cancel the original one within 1 hour under Account > My orders in the app or on the web.

And just a friendly reminder: previewing your book before ordering is always a good idea. Once an order is placed, we can’t make edits for you.
