Cannot view “My list” on Netflix - error ATV ui510-2

So I got the same error in both Netflix and Viaplay for a week. Nothing worked until I updated the AppleTV software. It was set to automatic updates, but I did it manually, and then it worked

I am facing the same issue with - getting the error ATV-ui510-2 when selecting “Suggestions” in Netflix using an Apple TV gen 3, as has been reported years back on and off. I have tried the obvious things to fix it with no luck. As I can read in a few of the threads, “Netflix is working on it” or “Apple is working on it”. Some even reports back that now it is working again, but they seem not to know what fixed it.

Sad that two so big tech companies are not able to reproduce the error and fix it. Guess they are earning too much money to even care.

I have bought a Chrome Cast instead, maybe that will fix it 🥳😂 Have not set it up yet.

UPDATE: played around a little longer. After searching for “2024” (random), clicking on a few movies reading the teasers and going back to “Suggestions”, it works again. For now at least.🤔🤷🏼‍♂️
