SoCal Jet Boats

Been using it for a few years now. It's been great, but been having issues with split orders. When splitting orders, it fulfills the order 100% in shopify with the first tracking number, then never updates shopfify when you fulfill further orders in shipworks. I contacted support and they said they had a previous feature request, but that request has been in the queue for over 3 years. Needless to say, I am looking for an alternative shipping solution.
