Ambient Occlusion only ‘sticks’ to main camera

I have an app where the user clicks on a ‘point of interest’ and the main camera tweens into alignment with a camera specific to that point of interest (poi camera), then switches active camera to the poi camera. Then they can ‘zoom out’ and the main camera snaps to the poi camera, becomes the active camera, and tweens back to the starting position. Works fine.

But when Ambient Occlusion is on, the AO shadows freeze in the position of the main camera, so when you orbit or pan or whatever with the poi camera, they look like a strange overlay over the image.

Here is the app:

My only guess is it only calculates it from the main camera.
