TuneIn and MyTuner radio stations have all disappeared

Most of my favourite radio stations disappeared from TuneIn and MyTuner this morning.

Most of them are still there on the MyTuner website but not in the MyTuner list on Sonos.

I am supposed to be able to add the streaming URL using the “add radio station” in the Sonos setup but it always returns “not encoded properly” when I try.

Does anyone know what hapened? Have these streaming services fallen out with Sonos or have they removed loads of radio stations?
