When an order is cancelled on Shopify, Shipturtle will automatically move that order to the Cancelled tab.
If a vendor cancels an order from their Shipturtle dashboard, the order will move to the Cancelled tab in Shipturtle, but it will not be cancelled on Shopify.
If a label is generated and an order is edited on Shopify, then the user will have to cancel the order and regenerate the shipping label.
