Depth of Field and visualizing DoF layers, not working

Hey Folks!
Depth of Field and the associated Visualizing DoF layers are not showing up in my project.
I followed and implemented suggestions from previous questions on same topic but nothing solved my problem.
Any suggestions ?

Were you able to sort this? I’ve having the same issue. Turning on DoF Visualizer in the ‘show’ menu does nothing.

I’m having the same issue. I’m pretty new to the program (using for film/tv effects) but have been on a deep-dive regarding why cinematic DOF isn’t working for me in any of my projects. My camera is a cinecam actor, I have all the aperture settings correct, I’ve got the focus plane consistently in the right spot. All scalability settings are at cinematic/epic.

Someone in another forum mentioned I need to turn scalability OFF entirely. Anyone know where to find this checkbox?
