Can't get AO to work with post process volume

Hi there,

I have attached the view of my scene in Buffer Visualisation and Lit mode.

I have ambient occlusion enabled everywhere I can think of, in the post-process volume, in the world settings, in the viewport and in the project settings.

The weird part is that I can see Ambient Occlusion through the Buffer Visualisation menu, and I can see the AO at work, however it won’t apply to my scene in ‘Lit’ mode.

Any help is appreciated!
