Hi, I have been trying to implement a paypal checkout whereby a button appears on the e-commerce site's "cart overview" page and when clicked, the user can pay for physical goods which will be shipped with tax applied in accordinance with their shipping location. I have implemented it all, except leaving the tax blank does not automatically apply the sales tax, and I can not see any API setting or option in the app/account configuration to turn this feature on. In my account settings I have already defined all the of the provincial tax rates that I am hoping to apply (shipping to Canadian provinces). The button is a "Smart Button", but I only seem to see this feature mentioned for the "Buy Now" button which does not seem to support dynamically pushing cart item prices. How can I get Paypal to automatically apply sales tax when pushing item subtotals?
