So does audio come from both the iPhone and TVat the same time?

Thanks I just checked and no such luck.

Tip: use Shortcuts to automate turning reduce white point on/off on iPhone/iPad based on whether you’re home or not. If I’m home (connected to wifi), it’s on but when I leave it automatically turn off. I have the accessibility shortcut mapped to a triple click of the power button for when I want to override but rarely need to. I wish similar could be done on AppleTV based on time of day instead as I’d only want this on at night. For now, I just have it enabled in the bedroom AppleTV.
