Why is Depth of Field and Motion Blur are not working with VR settings?

Depth of Field and Motion Blur Components working fine with Camera we use in Unity but when I import GoogleVRforUnity in Unity Project and applied it, the same components are not working anymore. Why??

@justinjkj sometimes you can get it to work by setting build player settings to multi-pass or single pass instanced (XR settings). Regular single pass usually doesn’t work for image effects.
