I found that the double tap only works on the home screen

Pixel XL tap to wake

Mine works wherever, if I leave an app open. Sometimes I think doze puts it to sleep though

Yeah, this is not accurate.

Definitely agree with Doze putting it to sleep though. Considering Doze didn't work for crap on my Nexus 5 and does a great job on the Pixel, I'll live with it
