She was in the television industry. She could have watched The Crown. It became apparent to Elizabeth from the time of her father’s death that “the family” was run by a professional staff whose mission was to serve and preserve the monarchy. Meghan should have known that’s how this family operates and if it wasn’t for her, turn down joining the family.
And she lived in Canada (an Anglophile country for sure) for many years.
So her claims of not realizing what the royal family was all about are pure bs.
