I don't think there is much to be said about this... you can review the app on Samsung's Galaxy App store yourself. It has over 1000+ reviews with 2 stars. Its been pathetic and for the longest time Spotify has done nothing to fix this. 

I've been a premium member of Spotify for awhile now and I rely on my Smartwatch and bluetooth headsets to listen to music OFFLINE. Which is a feature I pay as a premium member. 

Whats wrong with it ? For more than a year now the app has trouble understanding offline playable music. Although I've downloaded the playlist it keeps telling me I need to be online to play it. On occasions I've done some tricks to make it work but lately it just hasn't worked. 

Closing the app and re-opening it:

Does not work. If I am in airplane mode the app just hangs and tries to look for connection. 

Turn on wifi then turn it off:

I turn on wifi the app will load depending if there is internet connection on the Wifi. If not, it will also hang. There seems to be no period where it gives up connecting and just loads the app as offline mode. If it does load, I will select my playlist and a song (which is pre-downloaded) The song won't play because it needs to be online... even though the song I select has been downloaded to the watch itself.

Turn on wifi with internet, select a song, pause, turn off wifi:

This makes OFFLINE mode work sometimes. Unfortunately for some reason unknown the time. So when I do this procedure at home (with wifi) then head to the gym (with no wifi) it no longer works and hangs because there is no online.

Conclusion: I shouldn't have to do all these hacks and tricks to get offline mode to work. I shouldn't get to the gym put on my bluetooth earphones and realize Spotify is hanging or music is unplayable becuase I'm "offline" for my entire workout. Its quite embarassing for this 32bilion dollar tech company to be unable assign a single engineer to fix offline mode for the Spotify tizen app. You have 1000+ users on Samsung app store that says your app is garbage. I think the most single important bug to fix is offline mode. If airplane mode is enabled or internet is not detected it should KNOW to default to offline mode and be play music that is already downloaded. Community, if you are using Tizen OS, have a gear S3, or have a gear S product which runs on Tizen please up vote this and share to twitter, facebook, and social media. Its time to get some VPs attention here.
