Hello there, @Norbert_Davidt 
Recently, we had to make the reCAPTCHA mandatory for all widget with forms.
We had to make this decision because our widgets were receiving a large number of automated spam submissions. Emails and autoresponses were being sent to non-existent addresses, which caused the email provider to start limiting outgoing messages.
This affected email deliverability for all our customers, so the protection is now enabled by default and cannot be disabled. I am so sorry!
You can find more details about the current reCAPTCHA version used in the widgets and how your privacy policy should be updated due to these changes: Forms: reCAPTCHA Enterprise protection is now enabled.
Let me know if this explains things or if you have any questions left
