PSA: If having any issues with Unity Integration go to %appdata% and delete the Oculus folder.
PSA: Developers if you're having any issues go to %appdata% and delete the Oculus folder. Unity integration is being cached (wrong version). You'll spend days debugging the wrong code. This is probably a large part of the reason people think the Oculus Unity integration is so bad we've all been using the wrong version which has caused endless problems. Unity needs to serve up the current version and not just keep caching a bad version of the tools.
