Getting a blank Square checkout page while testing

I am generating a Square quick-pay checkout link with the Square sandbox create-payment-link tool. I am passing in the necessary parameters, and it is responding with a viable url, but when I visit the url, then click “Preview Link”, I am sent to a preview link page with nothing but a blank box (no product or payment being displayed), and “Secure payment by Square” at the bottom.

This used to work perfectly, displaying a payment, but as of about a week ago, it is no longer working as expected. I originally thought it was my fault but I believe there’s some kind of issue with Square. What’s going on here?
