My Rossini running Mosaic with the latest updates suddenly cannot lock on to Tidal, Qobuz, podcasts , radio. It does recognize the usb input and can navigate. I still have the previous app and that one works. The mosaic app worked yesterday. I tried the power down and also reinstalled the mosaic app on my phone and iPad. That did not work. The DAC still works through Roon.
Welcome. Check out other posts. Same was happening to me. It’s happening to everyone not just DCS users. But, just now, mine has come back. Something to do with Airable.
