I have a problem with a 10% discount code.
If customer adds product to cart, applies discount code and checks out then all is fine.
If customer adds product to cart, applies discount code then decides to continue shopping and adds further products, the discount is not applied to new products.
If the 'Refresh Qty' button is clicked in the cart then this error corrects itself.
See series of images...
Image 1 shows single product, discount (10%) applied and correct total.
Image 2 shows added product but total is now incorrect.
Image 3 shows corrected totals after qty refresh button has been clicked.
Any help gratefully received.
