For Nebs.nl I got a problem as below in the chrome dev

The problem is that the Cookiebot is hiding the Google reCaptcha because before allowing the consent. the reason is found here https://support.cookiebot.com/hc/en-us/community/posts/360006577259-Google-Recaptcha-field-only-loads-if-marketing-cookies-are-enabled

Your google recaptcha fields have been hided before giving consent because they set cookies on the site and therefore they are blocked until the user allows them. This is how Cookiebot works, it blocks/holds all cookies until the user allows them. 
In your case the google recaptcha is considered to set marketing cookies on the site and that is why the recatpcha fields are being hided before giving a consent regarding marketing cookies. 

To solve the problem, I go to the Cookiebot setting, General settings, Cookie blocking mode, set it to “Manual cookie-blocking mode” and then in the next section “Cookiebot script tag”, I select the defer option.

In this scenario, I load the Cookiebot after the Google reCaptcha, so the problem is solved.
