Automatic Driving Mode Not working as expected

[Gunner1737]

Automatic Driving Mode not working as expected for me. I am trying to have my Pixel 3 go into Driving Mode (Do Not Disturb) ONLY when a specific Bluetooth connection is active (and NOT when driving is detected). I have configured the specific BT device connection under "Automatic driving mode" settings and I have "when driving is detected" disabled, yet driving mode still activates DND when the BT device is NOT connected. I am guessing that motion detection is not really disabled, despite the setting. Is this a known bug and/or does anyone know a work-around? I've attached a screenshot of the settings in question. Thanks in advance!
