How to play playlists on HomePod?

Hello, I just bought a new HomePod, and the main thing I want to be able to do with it is play my playlists on both Apple Music on my iPad and iTunes on my MacBook.

When I say “Hey Siri play Playlist1” she doesn’t understand it. When I say “Hey Siri list my playlists”, she asks “What’s the name of the playlist”? No matter which playlist I name in reply, she can’t find it.

The home pod is set up and I can play songs from my Apple Music account on it, but I either have to specify the artist, song name, or just have Siri play random songs from my entire music library. But how do I play playlists exactly?

Is there some additional setup I need to do to make this happen?
