I have great news and not so good news for Pixel owners. I spent over 30 minutes trying different locking/unlocking scenarios, and my Pixel 7 mobile key works! This is even without the app open or running in the background. Now, the not so great news, the Pixel will try to kill some process (I'm not sure which one) when the app has been idle too long so you will constantly get the message to open the app again everytime it tries to kill this process. Damn you Pixel and your need to optimize my phone performance and battery!
