I tried it using your test card number. The pointer changes to a clickable hand, but like you said, nothing happens.
It’s possible this is a test-tool bug and not a site bug? But with it happening for other options too, I guess not. I’m not getting any error messages.
I’m new so am not useful here, but can verify that it’s happening.
The links on the bottom of the page aren’t working either. Is the URL set correctly everywhere. Sorry, that’s all I have.
