I have a new iPad mini 6th generation. Either I'm not understanding this feature or there is some kind of bug. My touch to unlock doesn't work. I can press the power button and it will recognize my finger print and unlock the device. I can also use toch to unlock when the iPad is on locked screen but won't work if the screen is asleep. I've factory reset the unit and I do have the touch to unlock turnned on in accessability. Verry Verry strange. I'm not sure if I should replace or wait it out until the next iPad os update. Guess I learned my lesson about being in the beta program but won't get in to that here of course.
