We encountered an issue with the API for buynow button generation. Our code executes the _cmd add calls correctly and adds the user selected items to the cart correctly, but when the user clicks on the generated buynow button it takes them to a page that appears to be behaving as if there are no items in the cart. A page displays to the user to add a description and amount for purchase. The quantity field also only shows a single item. The same code works as expected in the sandbox environment, but for some reason does not work correctly on the live system. Any insights into why the two environments would behave differently would be appreciated. Also, I'll add if the user performs a single selection or does a single item checkout things work as expected. It's only on a multiple item purchase and the live environment that things do not work as expected.
