Face unlock option unavailable

[gkitf16]

Just recently got the Nougat 7 update on my Nexus 6P via notification and installed it. No problems except the download is HUGE. I reset my PIN for the lock screen, it asked me to set up face recognition, so I did. But there is no face unlock option in the lock menu after doing so to use it! So I kept PIN and fingerprint methods on.
Prior to the update I was successfully using fingerprint and PIN unlocking. Never played with the face unlock before, so I don't know if that option got broken or removed in Nougat 7. Never activates the front camera when you press power button to use face unlock. How is it turned on, what could be blocking that option?

Is Smart Lock turned on? Facial recognition is used for Smart Lock, not for the usual lockscreen methods. https://support.google.com/nexus/answer/6093922?hl=en
