This is really frustrating and has me regretting wasting the money on Roon at this point. I have had this issue off and on since my subscription started last week. My network is strong and works perfectly through the Tidal app directly. Oddly my Tidal MQA playlist has no issues, but if I go into radio mode and a 16/44 Tidal track comes on it will play a few seconds then give me this message or just freeze entirely at the start.
