[Post Processing] Depth of Field issue on Android & WebGL

We are facing several issues related to post processing in unity 2017.1.0p4
For android the DOF effect does not work at all.
Whereas for WebGL , DOF is completely blurry / out of focus.
Please note that we are changing the screen resolution at run time (for optimization purpose)
Has any one faced similar issues ?? Please reply if there is any workaround for this bug.

I have the same issue, but as yet can’t find any solutions posted.

The ‘focus’ area goes completely black, as if it’s masking that part of the effect - but the mask is opaque instea of transparent.

I’m guessing it’s just (as yet) not supported by android in either the earlier version you had , or the current v2 version of the post processing stack on github.
