3dsmax 2020 Physical Camera Not Working in Arnold

I have lost hours tonight trying to figure out why I cant get the 3ds Max physical camera to work in Arnold. I want to be able to adjust lighting on a per camera basis. That would mean being able to use f-stop, shutter speed and ISO. I cannot seem to get these to impact the camera render no matter what exposure control settings I use in Exposure Control under Environment and Settings. The only way to impact a scene is with the EV compensation there but that is not per camera and I want to be able to use traditional camera adjustments in my camera just like I do with Vray. Any help would be appreciated.

Did you enable in Environment settings-> Exposure Control->Physical Camera Exposure Control and in Physical Camera Exposure Control->Use Physical Camera Controls if Available?
