Same issue here that happened just today, made sure I downloaded my playlist, went for a run and was able to play only the first song on the playlist. Restarting the watch, coming back and connecting to wifi and redownloading the playlist didn't help. Ended up running without any music, pretty awesome as that was the main reason why I bought them.
Thanks for all the feedback. I just spoke with Spotify support via twitter and I think have a solution. Disconnect the watch's Bluetooth connection to the phone and repair. Once I did that everything works as it should (for now at least). Can anyone verify this and report back before I tell Spotify it's resolved? Thanks.
I thought Spotify didn't need to use your phone to download your playlist and play offline, so not sure how that would really fix the issue and especially longterm. I bought my watch because I could download my Spotify Playlist directly from the Internet as advertised. It almost sounds as bad as Samsung telling us to reset our watch to default, which would also do extactly what you're saying. I don't want to sound negative and I appreciate you sharing, but Samsung and Spotify needs to get on the same page and fix the bugs with their products.
Ok, so I disconnected and then re-connected. At first, I thought this had worked as I connected my bluetooth headphones and went through a playlist going forward and back and it seemed to not have the problems I'd been seeing. I tried this with and without wireless and it seemed ok.
This morning I went to the gym and got 25 minutes into a run and then it stopped again. Firstly, when you are using a workout and swipe right to get to the song control screen, the controls on this screen do not work. Then I went to the spotify screen instead (no mean task when you're at full pelt on the treadmill) and tried here...Nothing but eventually after stabbing the buttons and play and forward/back, the music came back on and I managed to finish my run.
Then, I went to change playlists and that's when it fell apart. I just could not get another playlist (that I'd obviously downloaded) to play. The player looks stuck on Pause and no matter of button pressing does anything. I tried disconnected and then reconnecting - from my phone - nothing. In the end, I gave up and used spotify off my phone.
There is clearly an issue with the software and integration with Samsung health. I do not consider the disconnect/reconnect a long-term solution.
