I didint test it much, so I cant answer to your question sadly, but I want to touch on the topic of this functionality. Nothing, if youre listening, add more app support for this feature. For now we have apple music and Spotify, which is pretty weird since rather noone uses two music apps at the same time. Id love to have YouTube switch there, as much as Tidal since I use this one.
Also, would be nice to implement it cross devices, for example i watch YouTube from iPad, and using channel hop I could immidiately jump to music app on my phone. This feature have some nice potential if done correctly
