EDIT: Was able to fix myself. Hi everyone. I just set up two of my Sonos One speakers. I am able to play a lot of my music using my device (Samsung Note 10, Samsung music App). It seems to be able to detect a lot of my playlists. However I added some new music, and the Sonos app cannot detect the playlist. I also took a closer look and there are a few other playlists it cannot detect. A few times now I have done the “Update Music Index Now” feature and it seems to do nothing.
If anyone has any ideas I would really appreciate the help, Thank you
