I have Windows Hello facial recognition set up. After the latest update (1809), when I boot up my SP4, I get a message saying "Something went wrong. Please sign in with you PIN". At that point, I can type in my PIN to log in or I can click on the sign in options and choose facial recognition and it works fine. So I know my camera works fine and the facial recognition works also, just not initially right after the boot up. Anyone else ran into this issue and know how to fix it? Thanks!
