Recently I have found that the favorites list in Sonos has become corrupted with a subset of the song list recurring multiple times and I have not been able to clear this. I am using Deezer as my music provider and the favorite playlist there is fine, the problem exists on both my S1 and S2 equipment.
So far I have tried :-
1.Changing my Deezer password and reconnecting to the service and
2.Rebooting my router and all of my Sonos units
All to no avail, any suggestions gratefully received
