I have recently converted my music folder from MP4 to M3 and it is stored on my PC Windows 10.
Thispc/music/MP3
On setting the new pathway it has solved most problems but a lot of the tracks on Sonos playlists still show as MP4 (even though there is only one pathway to the MP3 folder) Some tracks on the playlists play some do not.
Have I missed something? Deleting and updating the playlists works but would take forever
