Pixel Perfect Camera not Working

I have tried everything I can think of in order to make the Pixel Perfect Camera work, but I have achieved nothing.

I thought it worked at first, but at the time of building the app I realized it did not work, it only worked in the editor because the reference ratio was 192*108 pixels.

The settings in my pixel perfect camera are:
-Assets Pixels per Unit: 32 - (All my sprites are set-up with 32 as the pixels per unit value)
-Reference Resolution:
-X: 192
-Y: 108
-Upscale Render Texture: False
-Pixel Snapping: True
-Crop Frame:
-X: False
-Y: False

I have tried out more settings, but it still does not want to work.

Does anybody know what could be happening?

I’m a bit rusty on all things Unity at the moment and haven’t used pixel perfect, but there are a couple of things wrong I spotted with that screen shot, firstly your camera ViewportRect aspect ratio should be W16 H9, not 1,1 and your reference Y resolution should be 108 you have 102.
Hope that helps
