After 17.5.1, I am no longer able to use the volume buttons to control devices connected to Spotify. I'm also having the same issue with the Sonos app. Please fix this, I was able to use them prior to the update.
iPhone 12 Pro Max, iOS 17
First, this is a user to user forum, not a way to ask anything of Apple. Second, there is nothing for Apple to fix, that is a Spotify problem, unless it is a Settings problem: Go to Settings/Sounds & Haptics and make sure Change with Buttons is ON. If it is, turn it off, restart your phone, and turn it back ON. If that doesn’t fix it, contact Spotify support.
