"Music Library Settings" missing

That’s great someone listened to you. First rule of Buisness..” listen to those that provide you with the means to do what you do”. I read your post and link.. they’ve never explained that to us in the UK. We shall see.. again actions speak louder than words. I still have to remove and reinstall Alexa to work my Spotify account almost everyday. Clearly there’s a lot wrong with core Buisness here. I do wonder if Sonos are interested in their customers really. 
 

keep us informed. Thank you for posting

Yes, it seems Music Library in the Android app appears just as mysteriously as it disappears. 

I'm having the exact same problem. Cannot access my music library, on a NAS, from the newly automatically updated app. The entire source selection and setup is missing. SONOS, this is a disaster! Access to my own music library is why I have SONOS and how I primarily use it.

Thanks for posting the email address. Here’s what I just wrote:

I have three Sonos amplifiers that I purchased to drive the 14 Sonos speakers that were wired into the house we bought three years ago, plus a Sonos:1 and a Sonos:3 that we'd had previously.

I don't use streaming services. I have a ton of music that I've digitized from rare vinyl albums that I will never find on Spotify or Amazon Music. I used to delight in playing these though the three Sonos zones I set up. But now I can't because there's no way to access my library. I continually get a 913 error when attempting to do so.

I now have $4000 of paperweights.

Your reputation is tanking faster than Tylenol after the poisoned pill crisis. At least they did something to redeem themselves. Will you?

Same for me - it's always been a second rate clunky app but at least the old version worked most of the time - the new one is a disaster that should be withdrawn immediately 

I posted an article with workarounds on medium. Basically - use the Plex Media Server until they fix this (who knows when).

I sent an email pointing out that their company deserves to go bankrupt for this appalling stuff up. There’s no way I’ll ever get a reply. Best way to make your annoyance felt is to do negative reviews on Amazon and anywhere else that sells their speakers. At least it will protect some other fools from making the mistake we have. 

I’m trying to do this but when I go to my music library directory (through windows explorer or through Sonia) there isn’t any little down arrow to select. 

Thanks, this is great, my NAS library is back again in Sonos through Plex 👍

I have seemingly related issues.  I have not even tried to define my music library using the new IOS or Android disasters.  I have defined it successfully using the app on my Mac.  My music library resides on a NAS.  Unfortunately, the  Mac app has also received the infernal blessing of Sonos and been updated.  So now, though the music library has been functioning for years with no problems, I periodically cannot find it.  IOS does not show it, either using the Sonos disaster or a third party app.  If I go to my Mac and look at the library setting, they are blank.  No library is defined.  So I get to re-enter path and credential information, and then wait while my music is indexed yet again.  I do not understand the rationale of creating a required support product that hinders the use of the main product line.
