Mine too, I have a Pixel 7 Pro and a Pixel Watch too.
The phone can't handle more than 2 connected devices so I purposely left my watch inside and made sure the phone wasn't connected to anything.
I turned off Bluetooth and tried to connect the digital key to the car. The app asked if it could turn on Bluetooth, I said yes and it connected straight away. Still doesn't start the car though.
I've done a factory reset on the head unit with no joy.
I've tried this method too, no dice.
It's booked into the garage in 3 weeks time as the USB C port never worked since I got it, there's a whistling noise at the rear passenger side, the LKA needs an update and the light sensor for the auto headlight is far too zealous. I'll see what they say about the digital key then.
I'd be interested to know if any other Trophy drivers have got it working though.
