The problem just happened again.
The browser on the TV did display Netflix at that point, as did my computer, which proves that it is the Netflix app on the Samsung TV that is the source of the error, not Netflix itself or any part of the network. Sadly viewing Netflix on the TV via the supplied Samsung browser is not a long term fix as controlling it without a keyboard or mouse using the TV remote is beyond excruciating.
Returning to the Netflix app and it took a cold boot of the TV to get it going again. I will be taking this up with Samsung. Wish me luck, I think I will be in for a whole lot of obfuscation, time-wasting and denial.
