I have a Samsung Smart TV. The Xfinity Stream App will not allow me to watch any On-Demand content. It says, “Sorry, something went wrong” with Error TVAPP-00148. This has been happening for some time. I’ve called and been connected with Advanced Repair and they weren’t successful in fixing this. We were on the phone for almost two hours. They said they’d call back but never did. I have the latest firmware/software on my TV, I’ve deleted and downloaded the app, I’ve reset the gateway, I’ve restarted the TV, yet nothing seems to work. Please help!
