Support weight over 25kg for AU and 70 pounds for US: This app breaks the cart items into multiple packages when it is over 25kg for AU and 70 pounds for US. And gets rates from sendle for individual packages and adds it and then returns the total as shipping cost in the checkout process . But in this case it will not book the shipment automatically, just add a note to the admin order timeline about this so that admin can book the shipment directly in sendle as per his choice.
