Yes I was trying to do it that way. Here is a link to the product page where I added the shortcode after following that guide.
You can see the shortcode right below the title. I inserted the product id of the master product. First one from the top though I am not sure what it's use it yet.
Is it because I have not created any categories and not imported any products as blogposts into my blog? I clicked on "Update Product and Settings" under Tools.
