The CEO of Sonos is PAtrick Spence and his email address is ceo@sonos.com

Maybe he is unaware of the absolute cods his team have made of the app and would welcome some feedback?

SONOS support published following. It looks like they didn’t develop yet a functionality listed below.

Why then they are pushing customers to update to undeveloped version?

 

Some say it’s because they are releasing headphones soon and they need this app to support it, current users be damned. 

I wrote to CEO and got response that they are fully aware of the problem and while they re working on it they suggested to use a web app as a workaround. 

The web app is no workaround, as it's responding way too slow.

It’s a piece of crap.
I have close to 1TB of music on my NAS and it plain don’t work. I get a list of the artists but nothing else.
They just need to revert to the old version and work out the kinks before forcing it on us all

I did just another Sonos update after the debacle update from last week, and now my music is gone from “your sources”.

i went on the Sonos app on my desktop and I see that my music folder is no longer listed, and won’t let me add another folder???

I too have the same issue. No functionality using my music library with IOs update rendering SONOS useless for my needs. I did voice my frustration with the “customer support” rep and explained that I understood he had nothing to do with the worthless update but to please send my complaint to VP app design/ R&D and it is my opinion he/she should be unemployed. I turned a blind eye when the original SONOS 2 update was incompatible with a perfectly functioning SONOS 5. I can no longer use all my SONOS speakers on the same app. I had to buy a “NEW” SONOS 5. (I’m sure that was the motive). This recent update makes all of my SONOS system completely pointless. I’m ready for a class action lawsuit for any attorneys interested in representing us. 

After several frustrating days with the new ios app, I checked the app on my iMac where my music is stored and was forced to update only to then not be allowed to add my music. I found a solution for the (913) error: https://en.community.sonos.com/controllers-and-music-services-229131/how-to-solve-the-error-913-music-library-on-a-mac 6894161#:~:text=Enable%20“Allow%20guest%20users%20to,access%20to%20guests%2C%20will%20work. This worked, but the ios app still won’t show my music. However, SonoPhone, a $2.99 app mentioned on this forum last week, works and now works with my music. Unfortunately, there is no global search and one must search each streaming service and the music library separately. Tomorrow, I’m going up to my second home in northern Wisconsin for a week, and I expect I’ll get frustrated trying to connect to my system there--It’s usually effortless.

Apparently the community post to fix the 913 error has been removed.

I have given up.  No response from SONOS at all and I can’t use my library.  I can only listen to Amazon and the same songs for so long.

My like for the 913 mac error fix may not work. Try this: 

Also, I can now report that Music Library shows up on the new Sonos ios app in “Your Sources” above Line-in’ --just took a while. No search, but alphabetical.
