I've been using the 'Back in Stock' integration for Shopify for a while now and it's been working fine, when a product isn't available the button appears and everything works fine.
Just recently with the last Chrome update (116), it stopped working (still works on Safari just fine),
What happens now is that when a product is not available the button displays like normal but nothing happens when the user clicks it, only a # appears in the URL as if the button was an anchor link.
This has been working fine until now, and I didn’t change anything else from the code.
