Building my Game, the Post Processing DOES NOT SHOW UP
Currently in the beginner stage of game, and added URP to the project. I only see the post processing in the SCENE view, not the GAME view. After Building the scene with my project, it doesn't show any of the post processing either, will explain if I do find answer out. The Top is the SCENE view and the bottom is the GAME view 
I'm on the same boat. In addition, I only see the postprocessing effect in the Editor on Windows, but not on MacOs.
