Where is my music library in the new app?

Dear SONOS, thank you for completely ruining my listening experience. When I first purchased my system 9 years ago, I was very excited about the sound quality and the ability to play music throughout the house with the app. Then a short while later, I was suddenly required to create an account in order to listen to the speakers that I OWN. Then a few years later, I was required to update the desktop app and completely re-import my music library. All this was tedious and aggravating but I got over it with just a lingering loathing for the company. Now you’ve updated the mobile app with a half-baked beta version that didn’t even have a volume control...I noticed that there now is a volume control, but not for streaming media. My only option there seems to be to stop playback and then sit through 3 minutes of ads when starting up again. Then there’s my personal music library. I couldn’t find it in the app so I looked on the desktop to see if an update was needed. What do I find, but that my music library folder has disappeared from the app. I have added the folder back and tried several times to import/update my library but nothing has worked. It doesn’t even appear to be trying to update. We’re having a party this weekend and now I won’t be able to play music on the patio. Seriously, you should really consider hiring some competent UX people!

Rest assured, I will never buy another SONOS product or recommend them to anyone I know!

You are probably using SMB v1 for a share.  You need to get your shares on SMB v2 or v3.  See this thread for a couple ideas:

I can always play my music from the Web App and the Desktop App.  It’s the ios App that is problematic and needs to be reset constantly to revive the share with my NAS.  Whenever leaving WiFi range, it always has an issue reconnecting and so I’ve pretty much given up using the ios App, other than to try it on occasion to see if there have been any updates.
