This happened to me today. I just bought my TV, Pandora worked for one song then stopped. I spent 45 minutes with Samsung and they ultimately said it was a Pandora issue. 

 @TannerPandora I just reached back out to Samsung as they left my ticket open and they told me to escalate to you. What can I do get this resolved?
