Hello @ryanbester77.
As the description details, the product code shows in the cart, the confirmation receipt, and the purchase record for each order in Woocommerce. If you are not seeing it under every order, likely you using a theme or plugin with formatting that is conflicting with the product code being displayed.
The first thing I would do is change the theme to WordPress default Twenty Twenty-Two and look at the orders to see if the theme is interfering. If that doesn’t reveal a difference, then disable cart plugins until you see the product code in the order and that will be the problem. Otherwise, it works for all the users we interact with.
Thanks!
