Note that, from the same cell phone; I was able access the file share using CX Explorer via the intranet wifi. I could also access the share from another PC over intranet wired network; all using the same share path and user credentials.
Hence it seems that this is neither a firewall, user permissions, nor a network /wifi issue.
I have also tried to restart my phone; as well as reinstalling the Sonos mobile app. Additionally, I have tried using a different phone - same issue (so it is not particular to my phone).
The file share is hosted on a Windows 10 (1809) PC.
Logically this seems to points to the Sonos app. Is this the culprit?
Anyone else having the same issue? Is there a fix?
Thanks for your time!

At the Windows 10 PC, go to Control Panel -> Programs & Features -> Turn Windows Features ON or OFF -> Checked the box for "SMB 1.0/CIFS File Sharing Support" to install the feature -> Restart PC
Hope this helps other users. Cheers and thanks again!
