The "trick" for this to work flawlessly (at least for myself) is to set up regular face-ID; and then setup an "alternate" appearance with sunglasses or whatever

The "trick" for this to work flawlessly (at least for myself) is to set up regular face-ID; and then setup an "alternate" appearance with sunglasses or whatever other items/accessories might cause problems. Never had any issues; especially if you setup the alternate appearance with a mask / partially obstructed face.
