My pandora music stops after 1 or 2 songs. I am playing it on my Roku. Have been using it for several years and it just started this. It plays on my phone and tablet fine. I have restarted Roku twice. I have removed it from Roku and re-installed it. Still doing the same thing. Also I cannot LOCK the sort to Alph any longer. It used to lock Alpha sort, but no longer. Tablet and Phone lock it fine. Is there some kind of upgrade to fix all this. Greg
