Oculus GearVR/Go online subsystem

Oculus subsystems work fine when i’m using an app id that corresponds to a Rift game and run the game. However when setting the app id to a GearVR/Go app and building onto a Go the entitlement always returns false.

I’ve seen a, relatively, old post which states that the plugin only works on Windows. Is this still true? If so is there any news on when it’ll be added in?
