Not woking on Contact Form 7 – Mar-2021

On a simple contact form, the form page refreshes even if the H-Captcha was not checked and filled in — but does not send the message. However, there is no error message to the user to indicate they MUST use the H-Captcha, or that the message cannot be sent without it. Thios leaves the sender with the impression the message was sent when it wasn’t — and loses business opportun ities and proispects.

Is there a way to make the filling in of the H- Captcha mandetory on the form with an error message appearing if the form is being sent without it?

Plugin is valuable only if it works — hope you can help.
