I have Android 10 on pixel 2xl with Gmail version 2019.08.18.267044774 and no option for dark them in settings.... Tried uninstalling and reinstalling too. 

I happen to love cilantro and I’m a 23 and me member. I don’t put much stock in any of the tests results that say you will be predisposed for certain traits or tastes, there often wrong. My genetic profile says I won’t like cilantro (I love it) , and I don’t have a clef chin or widows peak, I have both.
