Something I noticed after updating my Pixel 2 XL to Pi was that the toggle to turn NFC on/off was missing from the options under Connection Preferences. I don't know if this is a general bug or if mine is an isolated issue, but should anyone else notice (and care about) the same, rebooting into safe mode restored it, and it remained intact after restarting back into "normal".
