Why are my sales revenue data showing activity but the summary of pages/sales/downloads all show zero?

We pull the data directly from Amazon so what you see is accurate. One of the reasons for seeing inconsistent data like this is Amazon's reporting methods. While we don't have any insight into how they crunch their numbers it does appear that there can be a delay in reporting certain data. This is likely due to things like refunds, international transactions or error correction. This means that, in some cases some sales will take a couple of days to appear correctly in Amazon's KDP reports and, consequently, our reports.
