Screencast displaying Bluetooth settings interactions

SUMMARY

The toggles for enabling Bluetooth in settings appear not to work. Enabling both toggles does not give any option to pair a new device, though the system does acknowledge that a Bluetooth adapter is available. After closing the system settings window, both toggles revert to the off position.  

STEPS TO REPRODUCE
1.  Plug in USB Bluetooth adapter (ASUS), observe Bluetooth adapter notification
2.  Open system settings and enable Bluetooth with both the side panel toggle and the toggle on the Bluetooth settings window
3. Observe that no option appears to pair a new device

OBSERVED RESULT

No option to pair a new Bluetooth device appears when Bluetooth is enabled

EXPECTED RESULT

An option to pair a new Bluetooth device appears when Bluetooth is enabled
