Why can’t I automate Google playing a specific playlist on a specific speaker?

I want my morning playlist on Spotify to play in the kitchen when I wake up in the morning. I thought it would be straightforward but it’s driving me wild!

The playlist has a super specific name (not others, I checked) but Google keeps playing a random playlist instead. And despite setting up the automation to play on my kitchen speaker, this morning I woke to Gimme Gimme Gimme by ABBA going off on the speaker in my spare room (closest to me).

I know it’s possible because I have another automation to play a specific lullaby playlist and that works (though I trigger it manually instead of it being scheduled).

Any tips?
