Why can't I upload the RestockPro shipment plan file to Seller Central?

As of May 2021, Amazon changed the workflow for creating shipments in Seller Central, but the old workflow is still available. For now, RestockPro files must be uploaded to the old workflow.

To change to the old workflow in Seller Central:

  1. Click on link at the top of the page that says, "the old workflow will remain available."seller-central-old-shipment-workflow-1
  2. Fill out the survey, then click "Submit survey and go back to the previous workflow."seller-central-old-shipment-workflow-2
  3. On the next page, when you are ready to proceed, be sure to click "Go back to the previous workflow" again.seller-central-old-shipment-workflow-3
