I'm terribly sorry to hear this! Can you please reach out to me directly, I would like to verify what all troubleshooting steps have been performed and look into this further.
I have a 40 inch Smart TV I purchased in April of 2015. Until about 4 weeks ago, all apps worked perfectly. Now Netflix will not load - the program begins, but the app freezes after just a few seconds have elapsed. Netflix works fine, loads without incident on both Blu Ray players in the house. All other Smart TV apps - Hulu, Amazon, etc also load and work fine on the Smart TV. I have spent more than an hour on hold, spent and hour and 40 minutes on the phone while a technician worked with remote support. Nothing has changed, NF still freezes. About once a day I get a phone message from Samsung. If I am not home and the message goes to my machine, the technician calling speaks so quickly and in such a garbled fashion that I cannot understand what they are trying to tell me. I think there is a problem specific to Samsung and NF, but Samsung will not confirm that. Has anyone else had the problem during the last three months of 2015, and do you have any ideas? I would really, really like to know a way to bypass the wait queue on the Samsung support line, it feels like every time I contact them I go back to the beginning and start over.
