My phone key has been working perfectly since switching to a Pixel 3 about 10 months ago, after struggling with a Pixel 1 not working about half the time. I know there are well-documented phone key issues in the multitude of other threads and this isn't meant to re-hash those problems. I started noticing about a month ago that if I'm talking on the phone while approaching the car, the car does not sense it as the key and the doors will not unlock. I end up using my key card to get in to avoid having to hang up on the person I'm talking to since troubleshooting the phone's Bluetooth would start with toggling airplane mode. The phone won't connect as a Bluetooth audio device once I'm in the car until a few minutes later. If I'm not talking on the phone, none of this happens--the doors unlock and it connects as an audio device immediately, just as it should. Has anyone else experienced this?
