I am getting this message - since the past 3 or 4 days. Nothing has changed in my setup. I am running my music Via Tidal and its also now getting the message that track is not available from Tidal - which is not correct. It also shows song is playing on my phone and on my cocktail Audio DAC - but no sound coming thru. All this is new - never had any issues in the past with the exact same setup.
Also the song details dont refresh on my DAC sometimes - not always.
It sounds like a network issue for whatever reason (I understand that you changed nothing).
