There have been a variety of posts in the community before with people having consistent issues with Stingray Music over the years. For those who loved the music service but hated the repeated issues with it, thus eventually giving up on them (like I did), I’d highly recommend that you add the Stingray Music service back again and give them another try. I’ve been trying them for the past couple of weeks and the service has been super rock solid, better than they have ever been in the past. Seems like someone finally got serious on their end and fixed all of their backend incompatibility issues with Sonos.
