I have set up Siri to only come on when the iPhone is unlocked and through “Hey Siri”. But when using iPhone Mirroring on my Mac, I had assumed that when I authenticate with TouchID and unlock the iPhone, the iPhone for this purpose would be “unlocked” — I’m interacting with it after all. But it turns out, Siri will not come to life in iPhone Mirroring, no matter what I do.
