Thanks for coming to the Spotify Idea Exchange and voting to make this happen.
Тhis has been one of our most upvoted ideas and we've known it's something that our users would really like to see come true. We're happy to announce that this feature will now become available for the Apple Watch Series 3 or later.
It will be gradually rolled out, so it might take a bit until everybody has access to it. That being said, we'd like to let you know that the roll-out rate has increased a lot in the last weeks, so if you haven't received the feature in the past, try reinstalling the app on your watch again and there's a big chance you'll get Offline listening now.
Once again, thanks for helping us make Spotify better and voting to make this happen, here on the Community.
