The new offline mode is almost perfect and I'm wondering why shuffle and repeat are not available offline. This exclusion makes no sense to me, if the songs are downloaded then why should shuffling or repeating them be an issue. Please fix this soon or at least let us know of when this change might be implemented.
Just to reply on a previous post about newest songs not available / downloaded on the watch:
When you want to sync, go in your playlist on your gear, then go to the bottom of the playlist so that all the songs get to be displayed. I think it helps for the newest songs to be downloaded on the watch (this is empirical info...)
There was an update for Gear Fit 2 Pro last month, but it looks to only improve the fitness tracking apps. Gear S3 reportedly got an update to improve battery life. The Spotify app's development appears to have been abandoned immediately after its release.
Doesn't seem like Samsung is investing much developer time in these devices, unfortunately. At this point, I feel lucky if my Gear Fit 2 Pro even plays Spotify offline at all... works about 75% of the time.
