I use the Sonos Controller from a PC with the latest Sonos update installed.
I have all my music stored on a NAS drive.
What I usually do is update the iTunes library with new tracks and then go 'Update Music Library Now' so I can see my music available in Sonos.
Problem is that whenever I press on the 'Update Music Library Now' option, nothing happens i.e. the indexing doesn't start.
Only solution I found so far is to force Sonos to re-index the entire music folder by removing the music folder from the Music Library Settings and add it again. Works but not very elegant...
Note that the 'Update Music Library Now' option is NOT grayed out i.e. option is active but it doesn't initiate the indexing process.
Needless to say that the NAS drive is visible and has the permissions wide open.
Using the same exact Sonos setup, the 'Update Music Library Now' option used to work like a charm for years but for some reason it's no longer working since the last Sonos update.
I would like to avoid removing and adding the music folder every time I update iTunes library with new music.
