How to Cancel Spotify Premium on iPhone And I've removed the payment method, which means they won't be able to withdraw any more money from me the next time.

There - there you go.

In the future you could enter these two words on Google and you would immediately get to the Spotify page with the first search result.

→ Terminate Spotify

I think so often 😅

"Is Spotify Premium then automatically terminated, e.g. On Netflix?" - I couldn't find an answer to this question on Google. In the future, you could refrain from jumping to conclusions and making judgmental statements. 😉
