My understanding is National Geographic is supported. [This was reported in January](https://github.com/ytdl-org/youtube-dl/issues/18759), but it was immediately closed as "Duplicate" and I cannot find what it's a duplicate of. It appears to be the same issue. I was therefor unable to find if there is any kind of workaround.
