I used to keep all of my sonos system playing Classic FM radio station from London during the day. This was through Tune In. Sonos seems to have dropped this service. I was able to find some alternate classic fm stations through global player (although still not the live stream), for a couple of months. Now even these are no longer playing. Global player is still listed as one of my available services though nothing on it will come up in any searches and now no stations on it will play.

Thanks for the post and welcome to the community. Try removing Global Player as a service from the Sonos app and add it back in. If you are still having issues playing stations from Global player please submit a diagnostic report and reply back with the confirmation number.
