Replacement shaders on Oculus Quest

I'm trying to implement a replacement shader on the Oculus Quest. The shader is working in the editor with a rift but not on device. Does anyone know if there is a different process for using setReplacementShader on the Quest and where I can learn more about it?

Thanks
Dan

 

To attempt to shed light on my own question. Custom post processing on the Quest in Unity doesn't seem to be possible, and there is no word on if/when it will be possible
long open issue here :
https://github.com/Unity-Technologies/PostProcessing/issues/717
The official URP docs confirming that post processing v2 doesn't work. No details of a replacement :
https://docs.unity3d.com/Packages/c.../manual/integration-with-post-processing.html
According to this post there is a way to do post processing in the HDRP, so there is hope this will be ported to URP, but I can't find anywhere that says it will :

Any news on this issue?
