I mainly use my Sonos systems to stream from Spotify but recently I've noticed more and more songs in the Sonos app showed as greyed out and I'm am unable to play them.
Now before anyone mentions regions etc I should point out that in the Spotify app even running on the same device (i.e. phone, desktop or tablet) these songs aren't greyed out and can be played - even on a Sonos speaker.
They're simply greyed out in any of the Sonos apps.
My main play list has about 1200 songs on it and it used to be just a couple were greyed out which I put down to glitches, but this number is now in the hundreds making the app & playlist useless.
Anyone any ideas?
