I don’t understand why post processing is not working, I follow all the tuto and documentation and don’t find my error.  
I use URP as pipeline renderer.

I add a post process Layer on camera and set the layer to everything to be sure it works before creating a dedicated layer :

And add a post process volume to a empty gameObject in the scene wich is Global :

And sorry I forgot to mention that I check the checkbox PostProcessing on camera in rendering section

Using a volume instead of a post process volume works …
