I have a fully updated iPhone SE (2020) with an updated Spotify app. When I’m at work, I prefer to listen to Spotify via the web player on my work computer. During this time, the Spotify app on my phone isn’t open, and I always keep my phone volume on silent unless using headphones.

In the last few months, I’ve had a recurring issue where the iPhone app seems to be connecting to the web player without the app being opened at all, and this adjusts my iPhone volume to be the same as the web player volume on the computer. Is this an issue with Spotify Connect?

I don’t mind being able to skip songs and pause/play corn my phone while playing music on the computer, but I don’t want the phone volume to be affected. Is there a way to stop this without setting the phone app to “offline” manually?
