This usually happens because the software updates between the TV firmware, the Android TV operating system and the Netflix client are out of sync.


They need to register the TV and Android TV OS with some kind of email account so that all parts of the software receive updates. It's likely that Android as deprecated some software libraries and updated others and Netflix has updated their client client to use these new libraries. If the TV OS hasn't been updated but the Netflix client has Netflix is looking for libraries that are either out of date or missing in the OS.
