Made the fateful decision yesterday to finally update to the v80 app...ever since not only is Sirius XM non-functional in the iOS but now also Android & Desktop apps.
Yes I’ve reauthorized the app and also delete and readded the service in multiple apps (iOS & Desktop) and non-functional everywhere. Airplay streaming from SXM app itself is only current functional means of playing.
I have seen that there is a goose egg of help so far from Sonos, but hoping someone else as perhaps developed a functional workaround by now
