Yes, because that’s a live site I removed it.
Let me add it to the test site and share the link.
Here is the screenshot

I tried on incognito mode and 2 mobile devices but subscribe button not working.
When click on subscribe nothing happens
You can try it on this website https://beltrlux.com/
I just tried with the default theme and other themes but the result is the same. I regenerated the product lookup tables as soon as I click Regenerate it just reloads the page and nothing happen. It does not take any time I don’t know it’s regenerated properly or not but the issue still persists.
