In the case that your tracking number did not pull in from your shipment confirmation email, please report the issue here. To track your order, you will need to manually add a new order. To do so, click the + icon on your order history page and enter the tracking number you received.
If there is already a tracking number associated with your order that is incorrect, you will not be able to manually edit the existing tracking or add a new tracking number. In this case, you can also remove the order from the app and create a new order manually with the tracking number you wish to add.
