Google recaptcha not working on Mailpoet

Hi,

I was trying to change the captcha for our form. Instead of using the default captcha, we selected Google reCaptcha and activated it. I also followed the steps on this page https://kb.mailpoet.com/article/182-add-a-captcha-to-subscription-forms

However, when I test the form, it shows this error “An error occurred, make sure you have filled all the required fields.”

When I disabled the captcha, the test submission went successful. I enabled it again and added the reCaptcha keys but it didn’t work. Any help with this issue?

Thanks!
