I agree, all too often these days I either don't bother to use my Sonos or just keep listening to whatever was last selected rather than to wait for, or fight with the app.
I'm sitting here now looking at my Sonos, don't want to listen to what I had playing but also don't want the frustration of trying to find a favorite (mostly Amazon stations) that is still working.
I probably will play something once the spouse's TV starts to aggravate me more than the app.
