I had the same problem with Netflix/Samsung.
Below is the conversation with the Samsung support rep.
I did use a USB flash drive and updated the firmware. It did fix the problem...... or at least it seems.
(Oh, and BTW my tv can be remotely accessed!)
Please wait for a Samsung Agent to respond.

Rosemary: Hi, thanks for reaching out to Samsung tech support. How can I help you today?
Visitor: I am having trouble with Netflix. I have to login everytime I use it. It sounds like Samsung has this problem for a couple months.
Visitor: How do I fix it?
Rosemary: I am sorry to know that you need to login to Netflix each time you wish to access it.
Rosemary: Please provide the model number of the TV.
Visitor: just a moment
Visitor: where can i find it?
Visitor: can you do remote management?
Rosemary: You can find it on a label on the right edge or rear of the TV.
Rosemary: That can be verified with the model number of the TV.
Visitor: can i find it on the 'menu"?
Rosemary: Yes, if it is a TV after 2011.
Rosemary: Please try the step below:
Rosemary: Go to Menu >> Support >> contact Samsung >> Model Number.
Visitor: ok
Rosemary: Thank you.
Visitor: model UN55D6050
Rosemary: Are you able to access other apps without any issue?
Visitor: SOFTWARE VERSION T-GASAKUC-1022.4
Visitor: Yes all other apps.
Rosemary: The latest firmware for your TV is 1031.0.
Rosemary: Do you have an empty USB flash drive?
Visitor: uh..... no...
Visitor: can you go in remotely and fix it.
Visitor: this is our second home and I don't have a flash drive.
Visitor: When in the menu it won't allow me to do an upgrade.
Rosemary: I will check if this TV has remote management feature available.
Visitor: my tv says you can
Rosemary: I do not see an option available for remote management on your TV.
Rosemary: I checked an internal resource.
Rosemary: However, I will provide you the remote management number as well as the steps on how to update the firmware using the USB flash drive. Is that okay for you?
Visitor: 'the call center will access your samsung product remotely......"
Visitor: Are you going to send me the flash drive?
Rosemary: Okay. I recommend you contact our phone support at 1-800-SAMSUNG (726-7864); The remote management team is available 9:00am to 12:00am EST (Mon-Fri).
Visitor: ok
Rosemary: Not really. I can provide you the instructions if you have an empty USB flash drive.
Visitor: um go ahead
Rosemary: Thank you.
