Hello @FloydG ,
Could you please say what you would like to achieve?
If you need to limit hotspot registration only for the Embedded Browser per SK you do not need to set true for "open_default_browser_for_hotspot".
Also please check you have configured in Advanced settings "Allow hot spot registration" for Disconnected rule and set
"hotspot_detection_enabled = true " in trac_client_1.ttm.
After this you should Click on Connect button and Embedded Browser will be loaded to start the registration process.
