I have been a longtime SONOS user and SiriusXM subscriber, and have been able to connect to Sirius over SONOS for years.
However, I am being asked to re-authorize my Sirius account on SONOS. When I do, the Sirius authorization page says my account is not valid (“We don't recognize your username or password. Please try again.”). This happens whether I try to authorize my account from the SONOS mobile app or the SONDO desktop controller. The Sirius login information I have input is correct, because I am logged into my Sirius account on the same devices (desktop and mobile) using those same credentials. I also have the Sirius app on my phone and am logged into that with the same credentials.
I have tried deleting Sirius from my music services in SONOS and re-adding, but am getting the same error. Has anyone else experienced this, or does anyone know of a workaround?
