New Era 100 speakers. Alexa is set up ok if I ask it a question. But it won't play BBC sounds, or Apple Music. I can play both through the App, but I'd really like to just ask the speakers to open BBC sounds without going through the app. Ditto music through Apple.  Everything is linked per set up instructions.  As it's both BBC and Apple I suspect the issue is with Sonos, but I may be wrong. Any thoughts or suggestions gratefully received. Thanks.
