PostProcessVolume for iPad

Hi guys,

I wanted to do DOF for an IPad application but still can´t get it right. Anyone can help? From what I can see in the manual, it´s possible to create DOF for mobile devices. I am using PostProcessVolume (Focal Distance, Focal Region, Scale of 1) and I can see the results on the screen but neither in the preview for the mobile device nor in an IPad. I don´t know if there´s any specific DOF for mobile devices or if I should modify something in the configuration…

I am new to all this. Any ideas what to do?
