Hello @Marble772
It sounds like you were in a Premium Access session.
These sessions allow you to listen to on-demand content for a period of time. When the session ends, you'll automatically return to your free ad supported subscription.

If you'd like to return to listening to on-demand content, you'll need to activate another Premium Access session by listening to an ad.
