It says over here:
"Please note: if your regular form or pop-up form includes a follow-up email, a CAPTCHA will automatically be added to the form. To remove the CAPTCHA from the form, delete the follow-up emails in the Follow-up tab of the form editor.
And I want you to remove the auto recaptcha added on forms you use for follow up emails.
I think i suggested it already or someone else did.
Well I will wait till one of my collegues are back to see how we gonna proceed.
I heard there same block is made in your backend using your API. Still need to post a recaptcha in backend, which we want to go around somehow.
