Netflix error 11800 on Apple TV 4K - tvOS14.3

This error which appeared in the community 2020 is still occurring. Three cases last evening as we streamed a Netflix film. Stream stops with error - resume playing picks up OK and the stream continues until the next time.

My opinion is that Apple have to fix this - never happened before 14.3 update.

Netflix customer service via chat is a disappointing experience as they really don’t grasp what the issue is.

Apple support on this suggest deleting and reinstalling the app but why...?

The only app available is from AppStore and I’m at the currently available release.

Go figure - developers sort out v14.3 please
