The workaround below is not working either:
There currently appears to be an issue with BBC channels and Vtuner on Naim streaming devices. Here is a temporary work around for Naim customers to access BBC stations through the Naim app. Select the desired streamer via the Naim application Select the Internet radio icon at the top of the app Select the “Naim’s Choice” choice You will find at the bottom of this folder BBC radio 1-6 which will all work. Please use this as a work around until the regular service is restored.
