How do I get the old "Classic" user interface back?
To go to classic settings from new settings (as of application version 6.x.x), go to Settings > System Settings, disable the New User Interface toggle, and click Deactivate to confirm your selection. Any changes you make in classic settings will be permanent"
NOTE: The banner that may appear with a link to change the settings is not working in version 6.2.26. This is a known defect in this software version of the controller.
