Interesting issue. Since the new app cant add music library from hdd attached to an asus router whilst using the android app.

I keep getting permission denied messages (possibly because sonos seems to insist you type all details in and won't accept pasting) or it accepts the shared path and login id /password but then just hangs on the add share screen.

The shared path is //router name/Music

Under Music there are subfolders for each band.

If I select one band and add it, hey presto that bands albums/tracks are all added and play fine.

However if the band name has a space in the name  the add option hangs and nothing is added

e.g. //router name/Music/Led Zeppelin

It therefore appoears that Sonos cannot cope with the subfolders having a space in the name at that level and that is stopping the addition of the whole library.

If I try and add the library from a PC using the windows app I get a message that the location of the share has moved. This is complete nonsense and poor error reporting by Sonos.
