Thanks for visiting the Community.
@RachelGomez123, thanks for chiming in.
@Clever7300, since you've mentioned that you're using a Spotify Duo account, make sure that the other person's account is added as a home member of your Google Nest speakers. As soon as it is completely set up, you can follow these steps.
Do the same steps making sure that the right account on the Home app is selected.
Let us know how it goes.
