I have the same issue. If a "station is not currently available", would it kill ya to tell me WHICH station is the problem?
Why stop the whole feed and make me run in the other room to "dismiss" in order to continue listening? Why not just skip over an unavailable station when I'm in "shuffle stations" mode anyway?
Just happened to me again yesterday at 6:31 PM EDT. Took 4 clicks on the shuffle button before it played.
