We were experiencing an issue with the app not showing up in the Galaxy store. The issue should be resolved however. Make sure to keep your OS and the Spotify app up-to-date and the app should be back in the galaxy store.
Hope it is! Let us know if it's not or if you have further questions.
Have a nice day.
For weeks (even months) Spotify promises a solution to the problem. Then Spotify's solution to turns out to be to simply remove S2 from the list of supported devices?! In what sense is this a solution?! The app was provided but was then removed for no apparent reason. At the very least provide a workaround to use the old app, please!
