Both Sonos One and Echo Dot cannot play music via Sonos speakers. All is set-up correctly, speakers were found by Alexa Sonos skill and named Kitchen and Living. However, when I ask Alexa to play any music in Kitchen or in Living, she replies that she cannot find a device that is able to play music... the funny thing is: it does work occasionally, but fully at random it seems. Maybe once in 30 times or so. I have tried all kinds of resets, new installations, renaming speakers, re-enabling skills etc. Nothing seems to solve the issue. I first thought it might be the Sonos One that was the issue, but then I also got a Dot and that gave the same result. Who knows what this might be?

Wow! Indeed it was an authorization issue. I did delete the skills but reenabled them before deleting the devices. I now made sure devices were gone before reenabling sonos skill and got the geographic issue notification. It appeared that in my device settings on amazon.com my location was not yet set to us or uk. Changed it and now it works perfectly!!! Thanks for your help!
