happywriter on "[Plugin: WooCommerce] customized order confirmation email for each product"

I need to add special download instructions for a specific product. I wrote it in the "Advanced" "Purchase Note" portion of the product page, but the note doesn't appear upon purchase unless the page is refreshed and not always. Why doesn't the note appear in the order confirmation email? This would be easier than changing the code of the email.
