I skipped the building out of all the stuff in the tutorial. This site is just for me to figure out the Foxy integration before I convert a client's site from Webflow eCommerce to Foxy. We need downloadable products.
I'm not sure I understand what you mean. I'm using "foxy-foxy.foxycart.com" in my links, which is the subdomain in Store Details. Also, I have already added the custom code to both places where it needs to go.
