Here's my responce to my chase, they replied quickly at least. Everyone do the same:
We're sorry about the continued issues with your with your Galaxy Watch and Spotify.
We've checked and our tech folks are still looking into this issue with Samsung. Rest assure that a fix will be on its way soon. Please always make sure that your app and firmware have the latest version.
This is just soo annoying for far too long. The spotify pages state it would be working, apparently it is not. Further, it seems their most recent app versions are simply faulty or changed as it works with older spotify versions... Get this issue fixed asap!
