I have a premium account with Spotify and use an iphone (ios v 13.5.1) to control my ZP90 and Connect:AMP. When I attempt to add Spotify to my Sonos services, Sonos connects with Spotify and is successfully authorised however when Sonos then attempts to add the Spotify account it receives an error. All was working fine up until about two weeks ago. I have tried all the suggested solutions of rebooting routers, deleting and reloading Sonos and Spotify etc all to no avail.
Streaming Spotify through my Airport Express and using the Sonos Line In facility works okay.
Can anyone throw some light on how to fix my problem? I assume I should still be able to add a premium Spotify account to my Sonos S1 services. I can certainly add other services to Sonos S1.
