Why isn't my Pressero product using Embedded Services showing on my site?

My product is marked to active for the Embedded Service I am using, but it is not visible on the site.  Why won't the product show on the site?
This will happen when you have activated the product integration, but you have not set the site Integration as Live in Sites > [site name] > Settings > Embedded Services tab.  You must have *both* the "Is Live" and "Enabled" boxes checked for the product to show on the site.
