Amazon's reporting can take 24-48 hours to sync with our software, so your week-over-week metrics are using the most recent data available. These metrics are also using 1-day sale attribution to more effectively compare data from the most recent week to the prior week, which has had more time to accumulate sales with longer attribution windows.
Quick explanation regarding available data displayed in your notification week-over-week metrics.
