grecaptcha is not defined – what should I do?

Hi!

It is the first time I use CF7 plugin and first time I try to use recaptcha with WP.

I just got my recaptcha keys from google,
I set up the keys in CF7 Plugin Settings,
When I load the Form page, I got this error in the Console
Uncaught ReferenceError: grecaptcha is not defined
https://MYWEBSITE/wp-content/plugins/contact-form-7/modules/recaptcha/index.js?ver=5.9.3:1

I don’t see any I’m not a robot checkbox and the form is not working anymore.

– What should I do, did I miss any step in the set up of recaptcha ?

– Also the console.cloud.google (in Recaptcha Enterprise menu) ask me if I want to use the secret old key .
But the Contact Form 7 docs says I just have to enter the keys in the Settings and that’s all ? Is that right ?

Thank you for help
