Thanks for the report. It looks like your original music share is still there. Please head into the settings menu of your Sonos app, choose music library, and remove both shares. Then, add one share back. Once added, make sure to clear the queue before testing as the songs in the queue may be from the previous music share. Generally, if the share adds, it can play.
If that doesn't work, it's time to reach out to our phone team so they can take a closer look at this live.
