Hi All,
Yes, I have the Sonos app running from a Motorola G6 (Android) phone, using the B2 as the NAS music source and it works perfectly. I also have the Sonos app running from a MacBook Pro (High Sierra) without any problems.
What I did was as follows.
1. Sonos Front Screen (orange colour) --> 'Settings' --> 'System' --> 'Music Library' --> 'Music Library Setup' --> '+ Add Shared Music Folder'
2. A sub window opens up 'Add New Share' --> '\\192.168.1.60\music' --> Username: 'root', --> Password: 'brennan'. (don't use the quotes and substitute your B2's IP address)
3. If you go back to the 'System' --> 'Music Library' screen you will see a message 'Updating Music Index'. This will take a little while to complete.
4. Once the Sonos indexing completes, go into 'Music Library' and at bottom left of the screen tap on the musical note icon and that will take you to the B2's music listing.
Something to check is that in the 'System' screen --> 'Date & Time' I have ''Adjust for Daylight Savings' and 'Set Time from Internet' both switched on.
As a matter of note, if you go back into the 'Music Library Setup' you will see that the shared address now shows as '//
192.168.1.60/music' (note the forward slashes now). The app seems to do this.
@Rich, if you are still having problems it looks like the Sonos app and the iPhone are not authenticating correctly and the problem lies in there. Your B2 is functioning correctly, NAS is running, there is nothing more to do at the B2 end.
Regarding the 'Browse' button that you refer to, you will find 'Browse' when you open up the Sonos app, then on the bottom of the first screen, the second icon from the left is a 'musical note' symbol. Tap on that and the screen changes to the 'Browse' screen. There you will see 'Music Library' showing. Tap on that and this takes you into the B2 music content, but you will need to fix the authentication problem first. That lies somewhere between Apple and Sonos I think.
Regards,
Peter.
