Why aren't my most recent Walmart shipping label costs showing up?
The reason we don't get this information as often as we get order informations is because it comes from Walmart Marketplace's reconciliation reports, which, according to their docs, "are generated on the 8th day of every settlement end date. These reports are available in the Payments page to all sellers whose pay period is closed."
If you believe that there is still an issue, please email us at [email protected].
