User verification plugin – Always receive “Captcha not resolved” message on registration with reCAPTCHA v3

Hi,

With reCAPTCHA v3 in use, new users always receive the message "Captcha not resolved" when trying to register.  This results in them being unable to register.  It definitely used to work, but recently stopped.

Registration page:

Register/login

Please help.

Thanks.
Nathan.
