Are you using reCAPTCHA with other things? For example I believe you’re using Contact Form 7
I’m seeing this error in browser console: Error: Invalid site key or not loaded in api.js: 6LcPQ88ZAAAAADOXM2eHe4hrhy_... and it’s going through Contact Form 7’s js files
I think I fixed that Contact Form 7. Can you see on your end if it looks ok now? Even though I have added the right Google keys to that intergration, I still am not seeing the recaptcha box on the newsletter popup but maybe I’m missing a step?
I’m seeing the checkbox show up but it looks like it’s timing out with requests.

Can you test the form/embed on a normal page outside of a popup to see if that makes a difference?
I made just a normal page with that form and it works fine except it wants me to select a list to subscribe to. In the past, this wasn’t an issue. I had all the emails auto going to a list I selected, not the subscriber. Here’s the page:

Did you create a new form embed, or re-use the first one? Curious why it’s not finding a list to attach to if you’re re-using.
If you created a new form, it’s possible you forgot to choose a list to associate with? I’m not seeing one with the popup either which is also curious.
That said, at least the reCAPTCHA is working.
Any news or changes here?
