APP2 Three-way connection?

I had turned off BT on iPadPro while using APP2 on my iP14Pro for a phone call.
I was watching a conference via Zoom on iPadPro and saw chat notes that they could hear me talking even though I verified BT off on iPad.
About the same time, my wife started up our car in the garage and she starts hearing the same conversation.
How does this happen?

When you turned the Bluetooth off, was it in Settings > Bluetooth > turn the toggle off, or did you use Control Center?

If you used Control Center, when you turned off the Bluetooth, was the button solid white, or grayed out?


Turning off Bluetooth in the Control Center can lead to some odd behavior. Simply toggling it off will leave the button solid white, turning Bluetooth “off” until the next morning. However it’s not off, simply disconnecting most accessories EXCEPT for say, your Apple Pencil and potentially your AirPods.

That would be my first guess.

Intriguing notion, but no I went traditional settings/FT/toggle.
I do not remember anything like this with APP1 and just curious what could explain such behavior.
