Shortly after my last post, there were updates to both Pandora and Google (that is, the Google Assistant) on my phone. Since then, it seems to be playing a bit better, but still not quite right. Pandora still sometimes fails to open via the car Bluetooth, but not as frequently. More often, it will open, but to the last station I was listening to, not the one I just requested. And some of my other apps are starting to do the same, but not as frequently as Pandora. There does seem to be a correlation with whether or not the phone is on the lock screen, even though Smart Lock keeps it unlocked when the Bluetooth is connected. It seems far more likely to work correctly if I manually dismiss the lock screen before asking for the Pandora station. All told, I'm not sure what's going on here. Will keep you posted if I find anything.
