Recaptcha does not appear in my form

Hello,

I just follow steps to enable recaptcha in my site:

1.- I have key and password for Captcha v3 from Google.
2.- I fill fields in my site with settings from point 1.
3.- I enable recaptcha in my registration forms, in english and spanish.
4.- Also enable in login form.

I save all and recpatcha does not appear. Could you please help me?

Thank you in advance,

óscar
