Mobile Post Process Effects

My post process volume is not working on my android Pixel XL. I have followed the instructions outlined here…

Mobile HDR is enabled and **r.Mobile.TonemapperFilm **is set to 1. But the Color Grading is still not working on my device? Any thoughts?

PC(preview rendering level high-end mobile):


Mobile(Pixel XL):

Without Color Grading the scene looks very washed out.

I’m having the same issue, were you able to solve this?
