Incomplete Book Error while ordering a Book in Photos

Well there always is a first - but so far in ten or so years that message has been 100% correct - and no one but you can inspect the book to find the issue

have you previewed the book? Preview a print project in Photos or iPhoto to avoid issues - Apple Support

no one here can change anything - tell Apple what changes you would like - Product Feedback - AppleProduct Feedback - Apple -- we are users exactly like you have have exactly the same ability to make changes as you do

PS - that is one of the very few things that I have not yet seen happen - so far that message is always correct

If you have a message saying you have a missing photo then you do have a missing photo so you need to find it and you can nor order until you do - usually it is due to a user selecting a layout requiring a background photo which has not been added - if you have any gray layouts they require a photo - either add one or change to a layout that does not require a photo
