Improvement
We now synchronize shipping costs from Shopify just in time before generating and charging for each order. This makes sure that every order generated will have the most up-to-date shipping costs as configured in your Shopify store.
On top of that we now also continuously sync shipping costs from Shopify when any changes are made to a subscription’s products. This way you and your customer always have access to the most correct shipping rate that will be charged on their next order.
