Help with reCaptcha and Contact Form

Apparently Google failed the first auto-migration step:

1. A Google Cloud project is created to hold your existing keys.

There were no projects at all. Only when I created a new project, I could then see my old reCaptcha keys. Each had a button to upgrade. Also I had to enable ReCaptcha Enterprise API manualy - otherwise I couldn't even get into a dashboard

Unless I missed something

So I found a month old email, with a migration link. Clicked on it and then clicked a button to migrate. Other two keys were migrated, but integration still changed - it says to add:

https://www.google.com/recaptcha/enterprise.js

Among other things...
Maybe it's because I manually upgraded.. I don't know...

Anyway, I was also considering other alternatives (looking at Altcha), so I'll have to get back to it

Well recaptcha 2.0 started working again for me, without anything I did. So not sure what Google did, but it broke for a few weeks. Had not touched it on my side for many years.
