Post Process volume not working

I just noticed that my postprocessing volume stopped working.

only the GI and Ambient Occlusion tabs influences my scene!

  • Engine Scalability is set to epic

  • Mobile HDR is turned off

  • set to unbound

only a single postprocessing volume in the scene, which is enabled and has high priority!

Any Ideas on what might be my problem?

Have you checked to unbound ?

Yes! the strange thing is that AO and GI Changes is working.

Okay, after alot of testing, it seems like mobile HDR has to be enabled aswell as removing intermediate and Saved folders.
