Visit the Order History tab, select your order, scroll to the bottom of the page, and select I have a tracking number. You will then be able to add the tracking number associated with your order.
Note: Please ensure that the number you add is a valid tracking number and not your order number. The tracking number will be associated with a valid shipping carrier (such as USPS, UPS, etc.) An incorrect delivery date/location may show in the app if your order number is entered into this field.
