Thank you for reaching out. I can certainly understand wanting to be able to play YouTube Music from your watch and not your phone. After testing on my watch, I was able to verify you need to download the music from YouTube music and have a YouTube Premium subscription. Do you have the YouTube premium subscription?
Yes, I have youtube music premium. When selecting a downloaded track it takes me to a connected devices screen, pressing play on the track does the same.
Yes, these seem to be for streaming directly from the watch, but through a connected device, not the built-in speakers. (I still get the same thing when following them)
Thank you for that information. If you have tried all the troubleshooting steps provided, the next step would be to reach out to YouTube directly for further assistance.
