I've never heard an ad on Spotify, so this is true only for podcasts then, correct? In that case I can at least be thankful that Spotify is the worst option for listening to podcasts.
I canceled my Spotify premium subscription because they showed sponsored content in the app. Not as egregious as jamming ads in between songs, but I still don’t want to have to scroll past a “sponsored” UI element to get to what I’m actually interested in.
Moved to Apple Music and so far so good.
