How do I update the music library on the new app?

I am unable to update the Music Library on the new app,  I had the old gold app on another computer, when I tried to update the music library on that computer, the music library disappeared.  I found the folder deleted in the Sources, tried to re-add the folder in Music Library Settings and I get the error message “Sonos was unable to add the music folder”???

Ive had sonos products for years, using the S1 app in another location. The New app is too buggy to justify the Sonos expense.  I hope they fix this soon,  running out of patience. It should not be this difficult to figure out.

I am on an IPad and used to be able to update the music index, but it seems to have disappeared.

You have to use the desktop app to update the music index now, there is no mobile app support for this. Probably will come back at some in a month or so. At least I hope. 
 

Sonos removed support for smbv1 so if you previously used your set up with S1 you will need to enable smbv2/3 in your nas/share to make it work. 

Hello … I also came here searching for the answer to how to “Update Music Index” on the new App as it does not work as it used to? - After reading what @Bumper said above, I logged into the Sonos Controller on my laptop & was able to force a Music Library Update there (in Advanced Settings\Music Library Settings) by changing the time in Library Updates? - When I then restarted my App (Android) the album that I had just uploaded to my NAS was there & I can play it via Sonos Controller & Sonos App
Far from perfect, but beggars can’t be choosers!

I have 6 sonos products, and I’ve been a customer for 15+ years.  I used to listen to my music library on a daily basis.  Sonos team: PLEASE fix the issue & allow your customers to play music from their personal music libraries again!

OMG !!  This new app is horrible!!  I can’t do ANYTHING HERE!!  Please revert back and fix this crap!  

Music Library is back, thanks Sonos.

Though I see Music Library , how do I force a rescan of the music library on the IOS app after adding music.   Not a fan of the new App as it is missing far too many core features the old one had.

So where is the music library?  I do not see this on the desktop player setup or on the app on my phone.  I still have 15K songs on my computer that I cannot play.  Not a happy camper!!

I updated the IOS App (on iPhone and iPad) on 7/3 and got what I assume is the latest (6/22) App, and now I cannot see the Music Library at all.  I had an old version of the Windows App which has been working flawlessly, but it eventually required a software update to update the Music Library (which I didn’t do) but eventually the Music Library was empty (which has happened periodically for years) so I needed to update it, but it is now still empty so I cannot see the library from any device.  Are others seeing this?  It seems like some people can still see the music library as a Source in the IOS App.  Help!!
