I have a Sonos One and I am trying to use the NPROne skills for Alexa. When I say "Alexa, ask NPR One to play the latest news" Alexa responds "Okay. Playing latest news" and then nothing happens. I know Alexa support is still a bit iffy at this point. Is NPROne currently supported? Is there a list anywhere of things that are currently supported with Alexa and Sonos One (Which Alexa skills work)?
