I'm having the same issue .when I'm running and samsung health comes on to tell me my pace,time etc the music doesn't come back on .it can be 3km, 4km or 5km in .when I try to relaunch spotify the watch shuts down or freezes for 3/4 mins comes back on but still no sound .I then have to reboot.this is pathetic
I like so many bought a Samsung watch for the sake of spotify and have experienced nothing but grief trying to set it up.
If it helps, I found it works by doing the following
1) login: if you try to login with your usual spotify username and pw you'll have no luck. You need to search spotify device password. Login your usual spotify account on pc or phone and get taken to a account setting to set a device password. Once done you'll get an email confirming and which will give you your device use name which is actually a long number. Login with the number plus the pw you just created which is unique to devices/wearables only.
2) setup: login to spotify with wifi and Bluetooth enabled to sync and download offline content
3) use spotify without phone: turn off wifi on watch, turn off bluetooth on phone otherwise watch will connect to phones wifi via bluetooth. Then run spotify and offline playlist will work.
My understanding is if data connection breaks or changes whilst spotify is running, it kills the app. Therefore kill data before you use spotify and dont reconnect during use.
I can still use bluetooth headphones because I turned off wifi on watch and Bluetooth on phone leaving bluetooth on the watch.
I have a Gear S3 and have had similar issues. I can hit 'shuffle play' on a downloaded playlist in offline mode and it will start playing the first song (the same song every time). But after about 10 seconds it stops. I can skip to the next song and that will play for 10 seconds at most, but that's it. I cannot play any other songs, and the only music I get is 10 seconds on each of those two songs.
I tried disabling/renabling bluetooth and wifi with no luck. Someone suggested un-pairing/re-pairing with my phone but I'm hesitant to do that, as when I switched phones I lost most of my watch's settings.
I cannot believe that not even a single Spotify rep has commented on this thread. I like many others got the Gear S3 primarily for the offline Spotify functionality, and yet like many other premium subscribers I have to deal with the Gear S3 app that should never have passed QA and even then should have been fixed a long time ago.
I had the same prob. Before you plan to go offline you need to go into the offline menu then delete the cache of downloaded music. Then redownload your playlist again then go offline when compete and turn off wifi on watch. I've been doing this now for last ten offline sessions and works every time.
After many months of frustration since I bought the watch, I've had some success by doing the following:
1) I factory reset the watch - I did this not because I thought this would sort Spotify but I had one run where the GPS went mental and did not track my run properly so I just factory reset the thing to start again.
2) Obviously, I then re-installed everything, including Spotify and re-downloaded my offline music.
3) Now, here's the crux of things I think and what many people have said. You must turn off wifi before using offline in anger. In fact, I only turn the wifi on when I am syncing offline lists. In this way, I pretty much have 95% success rate in leaving my phone at home on a run and in the locker when I go to the gym.
So, where is the 5% failure?
Very occasionally, the player just stops pushing music to my bluetooth headset. I think this is a bluetooth issue with Spotify as if I have a backup playlist that I uploaded to the watch (in case this sort of thing happens) and if I switch to using this, it works immediately. To get around this, if you restart Spotify from the menu (not the widget), it seems to reconnect but clearly, mid-run, this is a pain.
I am not sure what causes this glitch out. Part of me thinks it is caused by sometimes changing the track and sometimes, as others have pointed out when Samsung assistant interrupts to tell you your split time and distance run so far (which you can turn off).
One thing that really does not work (again, with no wifi and on an offline list) and is very annoying is if you go into a playlist and use the bezel to scroll down, it just will not load any more tracks on the screen after say 12 or so tracks (works fine when connected to wifi) - This is very annoying as Shuffle does not work and so if you want to go to songs on the bottom of a long playlist, you need to literally press "Next track" 100's of times - This makes me seeth as clearly the tracks are there on the watch and work ok using the back/forward controls.
So, in summary, since I factory reset, I've been much happier and had a dozen or so gym visits and runs just using the watch and not having to take my phone. However, there are still some irritating things such as no shuffle and the bezel selection issue as well as the bluetooth dropout (which I'm not sure is Spotify's fault) that need sorting out.
