Oh, well, I will try to explain it better this time.
When you tell any deafie who hasn't joined Netflix that it has CC, then he/she's thinking " Oh, great, my TV has a built-in CC decoder as well as Netflix app so no problem for me, I want to join in".
After the person joins in, then finds out CC is not working while watching a streaming movie from Netflix, even TV's CC is turned on. He/she wonders why you say Netflix has CC. Eventually the person asks you again about CC, you would say "Oh, I mean subtitles". That's called misinformation. That's not right to misinform deafies like that before they join Netflix. When they hear or see "CC", they think it means a CC decoder is required. Hope you understand what I mean. I guess maybe I care too much.
