Your Kindle Direct Publishing Dashboard shows you daily sales numbers from your Kindle and Paperback books. These numbers do not relate to the Book Ad Report numbers on a daily basis. However, over a month period or more, they will match again.

The sales numbers from your amazon marketingservice campaign table are up to 14 days delayed. The official statement amazon gives is: “Campaign metrics may take up to 14 days to appear and do not include Kindle Unlimited or Kindle Owner Lending Library royalties generated by the ad.”

In my experience, the delay is only a few days.
