I have a new Playbase, along with an Echo Dot. The Echo Dot has been working fine controlling everything in the house. However when I try to add the Sonos speaker through Alexa it does not discover it...keeps saying "No new devices found." I go through Devices > Add a Device > Speaker > Sonos. The Sonos is connected and runs through TV as well as through the Sonos app. Just can't seem to get Alexa to "discover" it. What am I doing wrong?!
