Hello there,

Thank you for bringing this to our attention. I understand you are getting an error when trying to change your privacy settings. Where does it tell you that your account Is a child account? Are you not able to do things that you were able to do before this
service alert?

If you haven't already, try
managing your privacy settings straight from the console instead of the website.

Let us know the results.
