Post Processing Volume disappears when pawn take possess of the camera

Hi everyone, I have a problem: I made a post processing volume, everything works great while I’m in the editor, but when I press “play” and my pawn take possess of the “player 0” the PPV stops working.
I’ve found a couple of posts with the same issues, and the solution I found is “I think the Post Process Volume (PPV) on your character’s camera is overiding the other PPVs”, but this is everyting the other user wrote, and I can’t figure out how to do it, neither how to check if this is the issue.
Can you please tell me how to tell to the pawn to use my PPE instead of its?
Thank you so much

sorry for bothering, but UP
