For the owners of TDAI-3400: vTuner and Tidal Connect works correctly to you?
About vTuner I press and nothing happen while for Tidal Connect, I open the app on iPhone or iPad, they see the TDAI but If I choose it, nothing happen, the song won't start.
Roon, instead, works correctly everywhere.
Don't use vTuner, but Tidal Connect was working perfectly for me up until my subscription expired at the end of last week.
