I have implemented "Listen for Shipping Changes" from "https://developer.paypal.com/docs/checkout/integration-features/shipping-callback/" to adjust for tax and shipping differences and all seems to work fine except as soon as I activate it I loose all item detail inside the paypal window's cart. Instead of showing the quantity, name, sku and subtotal it just shows the name and subtotal and a "More" link which when pressed changes to "Less" but never shows the detail. The quantity is particularly important in our case. Has anybody else seen this?
