Reading Music Library

I’m trying the latest Volumio on an RPi3.
Music is an NFS Export from my NAS which is mounted OK by Volumio.
A large library - 118GB, 13,665 files & 1,013 folders
When I do Music Library > NAS > MUSIC (my main folder), I get a message that Volumio is updating the My Music database.
But then nothing - Music Library is empty.
There are no error messages.
Is there a limit on Library size?
Any help most welcome

Please ignore my previous post.
I was exporting an EMPTY folder!
Browse now has the turning circle and the Library is slowly updating
Apologies …

PS - The Volume control is not currently working but I suspect I haven’t yet found the correct settings
