Most likely, there is a single text element, image, or graphic somewhere in the workbook that extends beyond the allowed margins or touches Amazon’s minimum boundary. Since the book has many pages, it can be difficult to identify manually. I would recommend checking the pages one by one in the KDP Previewer. If you still cannot find it, you can hire a low-cost freelancer on Fiverr or Upwork to fix the file for you. This is usually a quick job for someone experienced with KDP formatting.

@Dennis Francis Hi, The fact that your normal product reviews are being published is actually a positive sign. It suggests that your account can still post reviews, while Amazon is simply taking longer to process the book reviews. I would not conclude yet that the algorithm is targeting your book reviews specifically. Book reviews are often moderated more strictly than ordinary product reviews. Even when the ebook was purchased for $0.99, the Verified Paid Purchase helps with review stability, but it does not guarantee immediate publication. Try reopening the book’s Amazon review page and clicking “Write a customer review” again. If your previous text and rating are still there, or Amazon says the review has already been submitted or is being processed, do not submit it again, as this could restart the process. If Amazon shows an error message instead, send the exact wording to our support team and we will help you check what is happening.

@Nikki Tresk Hi, This is very strange. There must have been an issue with Stripe, our payment processor. Since the payment attempt was declined, no additional charge was taken. Please contact our support team by email if this happens again, so we can investigate it immediately. In any case, you can be assured that if an incorrect duplicate charge is ever completed, we will refund it immediately. Many members of our community can confirm how seriously and correctly we handle situations like this.

Great approach. That is exactly the kind of behavior I recommend for keeping your activity natural. Usually, Verified Paid Purchase promotions are booked much faster, often within 24-48 hours. Which promotion type did you activate, and on your side does it currently show as Active or Booked?

In general, the best option is to use the Amazon account where you also make normal physical purchases, because that account looks more like a real customer account and is usually healthier than an account used only for ebooks and reviews. However, if your .com account was blocked from leaving reviews, the first thing I would check is whether the restriction is only affecting that marketplace or whether Amazon has restricted your reviewing ability more broadly. The easiest test is this: go to the Amazon marketplace you normally use for purchases, open the product page of any book or physical product, click “Write a customer review,” and see what happens. You do not need to actually post the review. Just check whether Amazon shows you the review form or whether it shows a message saying that they are no longer accepting reviews from your account. If the form appears, then the account may still be able to post reviews, and in that case I would use the account connected to your normal physical purchases and move carefully, focusing as much as possible on Verified Paid Purchase reviews. If Amazon shows the restriction message there too, then the issue is probably not just .com, but your reviewing permission on the account more generally.
