recaptcha and Moodle

Moodle has a feature of enabling Recaptcha for email-based registration. But when I tried it with the v3 version of the google captcha, it did not work. V2 works. So, go to recaptcha site, click through the options, choose v2 and not v3

(Moodle seems to have issues with v3? or was it that I did not wait a sufficient amount of time for the changes to propagate?)
