Netflix app becomes slow on Apple TV

I have a 4th generation Apple TV HD. I have no issues except with the Netflix app. I have a rather lengthy "My List" and ever since they deployed their ribbon interface I've had issues. After I've watched a video and return to the list, the longer I scroll, the scrolling begins to slow down. Over time, it slows so much that the app becomes unresponsive.

The only way to get it going again is to restart the Apple TV. I have no issues with other apps, only Netflix.

I contacted Netflix and after going through the usual motions, restart this and restart that, and explaining I'd done all this and that and telling them this app will work fine for now but act up later, their response was to contact Apple. Contact Apple? Netflix is the only app acting up. They asked if the problem is seen on other apps. I said my Mac is the only other place I watch Netflix. They responded, "Ah, the issue is the Apple TV since it works fine on your Mac."

"Seriously?" I said. The technology is different for each device. One is on a browser, the other is a device specific app. But they stuck with their mantra. Obviously, they're clueless and unwilling to expedite such issues to their app development team. Very pitiful customer service.

So I'm asking everyone here, is anyone else experiencing a Netflix app that runs ever more slowly the longer they use it? It acts like the app is sucking up memory until there's no more available, causing the scrolling to eventually stop scrolling, followed by the app becoming unresponsive all together.
