GearVR build only works in Left Eye

Hello! I have successfully deployed my GearVR App, but only the left eye displays an image, and the right eye is black. The left eye displays the HMD split screen, as if it were both screens for both eyes. Any ideas as to why this happens?

Upgrading to 4.9 fixed this. Not sure what was the cause.

You probably have both the Oculus Rift and HMD plugin enabled under windows → Plugins → Virtual Reality

Hope that helps
