It's not known what meeting Harry was referring to - and whether it did or did not take place.
Speaking to the Daily Star, the expert said Harry replied: "It's sad. I'm fed up, I've tried talking to him."
It's likely that Harry was speaking about King Charles or Prince William, but there is bad blood with his father and brother.
It's then claimed that the pair had another chat later on while they waited for the new King and Queen to arrive at Westminster Abbey.

Quoted excerpt below:
A lip reader picked up on the moment where Jack asked Harry: "The meeting?"
The lip reader believes Harry replied to an unknown question from Jack which was referring to Meghan, saying: "No, she's at ..."
While tilting his head, Jack supposedly asked: "And is she?"
Nodding to confirm, Harry added: "It's not ideal."
"If it makes [you] feel any better even I can do it," Jack is believed to have told Harry. "It's not quite the life, is it?"
Harry then shook his head as Jack seemingly said: "I haven't had time for that, not if it's over..."
Then the Duke of Sussex made a very cryptic comment, saying: "It's an eventuality."
