Why isn't the ID.me verification button working on my landing page?

I installed the id.me app to offer military discounts. I enabled the landing page option in the app settings.

But when I go to the page on our site and click the “verify with id.me” button, nothing happens.

The cart integration is working fine, and the button there pops up the id.me verification window. But the landing page button does not work.

When I look at the code in the cart that IS working, I see this:

ID.me ID.me

When I look at the code on the landing page that IS NOT working, I see this:

Verify with ID.me

Clicking the link just loads our page with the #%7B@shop.checkpoint%7D/verified tacked on the end.

Thanks for any help!
