The user that use https to push back to repositories is getting an error:
remote: Warning! remote: You are currently connecting with your team account. remote: This is no longer supported, so please connect using your user account.
This occurs because the team account repositories are using GitAuthProxy to generate an access token for team account which is going to be deprecated soon and causes the above error. However, if the user is pushing using https it can be ignored as the change is still being made even with the error.
