At some point my preview stopped showing the view based on the actual camera angle. If I rotate the camera, the preview does not change. I think this started when I added a billboard, which also added an ortho camera. I need to be able to preview through the original camera correctly so that I can adjust animations that are not visible in the view that the preview is stuck on.

Happy creating!
Hi there! Likely you created an Empty Project which does not include tracking by default. To add tracking, select your camera object in the Objects Panel. Then, add a "Device Tracking" component to the camera and make sure Surface is selected in the tracking type dropdown. The object should now be tracked to the world. Note, all of the world template have this setup by default so I recommend starting from their if you're working with a world experience. More info on tracking can be found here:

Actually the problem was the opposite, but maybe you misunderstood the question. I had to disable the tracking in order for the preview to show things based on how I rotate the camera in the editor. Then of course I had to re-enable it so that it worked properly for run-time.
Ah, yes. Device tracking completely takes over the camera's transform. When using device tracking in the scene you can't modify the camera's position / rotation. Glad you found a workaround!
