When I ask my display to "play [channel] on YouTube TV, I get a message that a subscription is required. I have a paid subscription to YTTV. If I ask it to play YTTV without specifying a channel, it works, and then I may be able to navigate to the channel I wish to watch, via the voice commend I first mentioned.
This started a few weeks ago.
I have rebooted the device, as well as my router.
