Recaptcha v3 not working so well

Hiya

I’ve upgraded the Google recaptcha keys for my websites to version 3 and installed them in the ‘Contact Form’ – ‘Integration’ section. With the v2 keys, I never got spam from my contact forms. Now, the spam is starting to flow. I look after about 60 websites for myself and my clients. None of us will be happy if we get daily spam.

How can we tighten the security?

Thanks
Jackie
