Adding review link into an existing flow

Hello!

I've already given up on reviewing multiple products in one email, I would settle for reviewing just the first product. However, it simply refuses to work. When I preview it, it looks fine. Even when I send it as a test, it navigates there and looks good. However, when I do a test purchase and the email comes that way, the product image isn't there, and no matter how much I click on the stars, it doesn't navigate to the review page. Why? What am I doing wrong?
