I have 5 locations including one default 'Unassigned' location where orders are assigned the other locations for shipment. However, some orders are coming through automatically assigned to a location other than the default location. Is there a hierarchy that Shopify uses when assigning to a location other than the default. For example, if the item is not stocked at the default location, does it automatically assign to the location with the most SOH? I am trying to keep orders from being assigned to other locations until I have manually changed the location from the default.
