New Apple TV remote shuts tv off then turns it back on
I have the first gen Apple TV 4K and just recently got the 3rd gen remote to replace my old one. My Apple TV box is connected to a Samsung tv. I successfully connected the new remote to the Apple TV. I used to be able to turn off the Apple TV and Samsung tv by using my Samsung remote power button to shut everything off. Now though, when I try to power off the Apple TV and the Samsung TV with either remote, it shuts everything off temporarily and then almost immediately turns back on. What should I do?
