I had a number of SomaFM stations in “My Live Radio”. I was playing one of them (Space Station Soma) yesterday. This morning - all of them show “Station No Longer Exists” when attempting to play. The stations are playable by going to the SomaFM website and manually re-adding using a URL for the stream.
If I search for SomaFM within Roon - nothing of any use comes back.
