Hi Ashley, As Zweitze mentioned, you could revoke that user's access in the specific account. If you need the user to have access and if he/she is not making these changes intentionally or some application which the he/she had authenticated previously is making theses changes, the user could go to this link <https://myaccount.google.com/permissions?pli=1> and revoke access to any suspicious application. Revoking access to the application will invalidate all the refresh tokens issued to that application and you will need to reauthorize in order to make any new API calls.
Could you share the client customer Id and the date on which these changes occured? I can check if these were being made using the API. You could reply privately to author while sharing the details.
