FAQ: Why are Amazon reviews taking so long to come in?
Amazon has implemented changes to their review system that will often result in a delay for reviews to be posted. We've seen this take up to 10 days. It's not ideal, but there's nothing Booksprout or reviewers can do about it.
Our recommendation is to wait patiently for reviews to come in. Reviewers will often contact you to let you know that they've posted their review, but it's not live yet.
