Apple Watch users who like to use Spotify to stream music should not update their devices to watchOS 9, because the bug will cause streaming on the watch to stop working.
Spotify Music sent an email to its subscribers warning of the issue, which began shortly after the official push of watchOS 9. Spotify said.
"Apple WatchOS 9 introduces a bug that causes Spotify streaming on Apple Watch to stop working. We strongly urge Spotify Apple Watch users not to install the WatchOS 9 update until Apple resolves the issue. Users who are already affected can download their content to their Apple Watch and listen offline or stream it from their phone."
According to user reports, streaming on Apple Watch stops working within the first minute, but the track progress bar continues to move, just minus the audio. both Wi-Fi and cellular connections have issues, but Spotify media downloaded to Apple Watch has no issues.
Apple has released watchOS 9.1 Beta for developers this week, and there are unconfirmed reports that the Spotify streaming issue has been resolved. However, Apple did not mention the issue in its release notes, so we won’t know for sure if the bug has been resolved until Apple rolls out the next Apple Watch update to the public.
