I'm putting this out there in case anyone has a similar problem.
I have a 2011 Samsung and right now I use the Smart TV features for Netflix only. (DIRECTV boxes have Pandora and YouTube, and I'm not subscribing to the other services right now.)
I have a very specific, and 100% repeatable, issue.
So, I'm watching a TV show (that has episodes, not a movie.) If I watch more than about 10 minutes of the show, when I come back to the netflix menu I don't get the familiar "Watch S2:E8/More episodes/Rate this..." menu. Instead I get the animated "busy" graphic and it never goes away.
If I then go back to the netflix main menu and select a movie, then stop that and go back to the original show, then the menus work.
It's like something crashes in the app and doesn't get reloaded unless I go to something that doesn't have episodes.
It's not the connection, I can use my Samsung Smart Blu-ray player which is on the same switch and it doesn't have the problem. (But, it is 4x slower in bringing up menus.) It's not the software version, I'm on the latest.
Samsung turfed me over to Netflix, Netflix turfed me over to Samsung.
Has anyone else seen this? So far the likely fix will be adding an Apple TV box to the mix.
