Been using Plex/Sonos for a long time. All good. Today, out of a sudden, connection to Plex was lost. I deleted Plex then tried to add it as a service. After I successfully authenticate to Plex and go back to the Sonos dialog, the NEXT button is greyed out. I cannot click on it to continue adding the service.
This happens on multiple versions of Windows and on my mobiles.
Any idea/help? Sonos support was unable to help at all....!!
