Apple WatchOS 9 introduced a bug that causes Spotify streaming on the Apple Watch to stop working. We urge Spotify Apple Watch users not to install the WatchOS 9 update until Apple has implemented a fix for the issue. Users who are already affected can instead download their content to their Apple Watch and listen offline or stream from their phones.
