What happened to the music app?

Last night, my watch automatically updated to 6.10. Afterwards, I got a message on my watch to log on to Spotify. First, I did not add Spotify to my watch. Second, the source icon in the music app is suddenly nowhere to be found, and although my music is still on my watch, nothing will play. Under Music Providers, I just get a screen telling me to go to Garmin Connect Mobile to add music providers, with no way to access the music that is actually on my watch. Worked perfectly before the update. WTF Garmin?
