So not sure what has caused this issue in the app (I have recently updated to an S20+ and readded Spotify to my Samsung watch), but when I want to play a song from a playlist the song showing won't play but another from my playlist will. Also the bar at the bottom of the app will show the song that I have clicked on but will not show the pause just the play button (even though a song is playing) and the white progress bar won't move. In order to pause the song playing I have to press the play button three times. I can manually move the progress bar and it will fast forward or rewind. I have logged out and back in again, force closed the app and even uninstalled/reinstalled it. I am on android.
