Hey Tobi,
Thanks for letting us know. We've received a ticket via our support team that is similar to this issue but if that isn't you, please reach out to us at support@funcaptcha.com. We're happy to help any time.
Thanks,
The FunCaptcha Team
We've been hearing this from a lot of our newer clients - they make the switch and tell us their old reCAPTCHA just didn't seem to cut it. Are you using the "No CAPTCHA reCAPTCHA" updated version Allan?
