I am unable to add new content services. Trying to add BBC Sounds, Spotify and Amazon Music. In each case, I get redirected from the Sonos app to the provider to authorise the connection and am told that the service has been added successfully. But when I return to the Sonos app I get an error message saying the service has not been added.
I am using the Sonos app on Android and have 2 Era300s in a stereo pair and a Play3
