Not only does it work, but it was the only way I could setup my Apple TV 4. I had to borrow the old remote off my uncle as I was away visiting family and had time to set it up and play with it. When booting it up multiple times, it wouldn't connect to the new BT remote. It just jumped straight to the country selection screen. Tried holding down the buttons to re-pair, tried charging the remote for hours. Nothing worked until I tried the old remote. Was able to use it to complete setup and boom, the thing connects like it's no big deal. As a tech person I was really scratching my head over this one for a while, so I can't imagine what a normal person would do—especially if they don't have an old one. I didn't have a USB-C cable to connect it to my MBP to fix it that way but that old IR remote did the trick!
