Hey there! The additional scripts for Shopify Checkout has been deprecated and you can now customize the thank you page from within the Shopify theme editor. In the theme editor select the drop down menu from the top and choose checkout. This will take you to the checkout editor and from there you can customize the checkout appearance and the thank you page.
