I started experiencing it about a month earlier on my 65 inch samsung in living room. Reinstalled several times, it would play one song and then go mute. Tried everything suggested and even reset the tv to factory default and reinstalled all apps. No help. Installed it on my smaller samsung tv in bedroom as a work around and it worked fine so know it is is not network. I just tried going in to my pandora account and I hit the option to log out all other devices from my pc. I then changed my password while I was in there. Then I went to my phone app and logged in and then went to my app on the living room TV and reactivated app and it seems to be working now.
