I am unable to get my magic remote on my oledc9 to control my Apple TV 4K. There is no simplelink option in my menus despite seeing this in YouTube videos and LG help guides. I’ve set up device connector and I can see the white light flicker on the Apple TV when I move left or right on the magic remote but it doesn’t control it. I’ve turned on home theatre remote control in the Apple TV remote settings. I’ve tried a new HDMI cable. I’m stumped!
