The orders shipped after this setup will not be updated to the marketplace until you review the orders and manually mark the review completed. This workflow gives you a final chance to review the shipping label, submit the order with label to a WMS/3PL software that we integrate, etc. before the order is marked as shipped and tracking number uploaded back to marketplace.

The pending review orders are listed on the pages under the Review menu. You can simply go to the Normal page to review all the orders instead of navigating to each order queue pages.

Once you finish reviewing the orders, make sure to select them and click the "Mark Order Review Done" button on the top.
