I have created a shipment but need to change the ship date.
Step 1: Void this label first. Go to “Shipments”, select this tracking and click “Void”.
Step 2：Go to “Orders” and find the original order to create a new label.
Step 3: Click “ship order” (Or you can also edit customer information on this page)
Step 4: Choose the Ship Date-Create Label

When you are on this page, you can choose the ship date as you like.
