Hi, Thank you for reaching out. The link you sent me clearly shows that the SET operator is not supported in this method. The MutateMembersOperation represents a request to add or remove members from a user list. As for the REMOVE operation, you could change the operator to REMOVE here and change other codes accordingly. Once the user list is removed, you would need to create a new user list with a new userListId. Please bear in mind that the API does not necessarily always have the same functionality as the Google Ads UI. The Member object does not contain the size field. However, you could get this data when you create a new user list by checking the member size. In order to add new email, you would need to create a new user list with the new email rather than just add the email to the existing user list.
I hope this helps.
