I have integrated Tidal into my Roon library for almost two years.
A few days ago, every Tidal track I select and try to play gives me “This track not available from Tidal” even though album covers and track selection show up in my library. Worked great with my Mac Mini (for two years) and with my Nucleus (four two months) until now. Wired network wireless network are unchanged, cables are the same, location is the same.
Only difference? Last week my debit card was hacked; I added a new one. Tidal account is listed as "Successfully signed in; library sync is OK; I disabled and reconnected.
