Just got my first Alexa (Echo Show) a couple of weeks ago. Only use it for listening to BBC Radio 4. Previously installed BBC radio skill and successfully authorised device. All working fine.
As of yesterday evening Alexa cannot play/find *any* BBC radio station. All other radio stations play fine. Saying "Alexa, play [BBC] radio 4/3/2/1" or just "Radio 4" is either greeted by playing some obscure radio station or "cannot find that radio station". Unplugged/rebooted Echo, no difference.
I have done my usual Googling research, and cannot find anything, and certainly not since yesterday.
What has changed since yesterday morning, when it all worked fine?? What do I do?
