The Duke and Duchess of Sussex "didn't see it coming", according to an insider. The monarch, who opposed a half-in half-out scenario, is said to have stunned the pair with the harsh measures last week as Megxit was confirmed.
The decision has reportedly impacted Meghan and Harry's upcoming interview with Oprah which now needs to be re-edited.
It is understood the former actress and the Queen's grandson spoke about their roles in the monarchy which have "significantly" changed following filming earlier in the week.
CBS wants to re-shoot some of the interview in light of the Megxit announcement, the source said.
The insider told the Mirror: "When the Duke and Duchess spoke, it was never envisaged they would have their patronages taken away.

"Now, however, other than their titles, they are to have no role in royal life - a point producers know was not discussed when Winfrey spoke to them.
"Neither the Sussexes nor the TV crew saw the fallout of their interview leading to this. Harry and Meghan thought they would retain their roles.
"But things have significantly changed for them since they eagerly sat for Winfrey and poured their hearts out."
Meghan and Harry's interview with Oprah airs on CBS on March 7.
The couple - who are living in California and expecting their second child - quit royal duties in March 2020 for a new life of personal and financial freedom.

1.15pm update: Meghan and Harry's 'horribly disrespectful' retort to Queen defended
Meghan Markle and Prince Harry's latest statement on service should be "taken in context" of the Duke and Duchess of Sussex's love for philanthropy and the charity work they'll be able to do following Megxit, according to a friend.
Former British Special Forces soldier Harry Dean Stott told BBC Radio 4's Today Programme: "We're all focusing on them stepping back.
"I made some comments last year that there are so many positives we can take from this, especially their love for philanthropy.
"Obviously them being within the royal spotlight, there's a lot of protocol and red tape.
"But actually, their decision to step back gives them more opportunity and freedom to do more and help more. So I think [the statement] is probably taken in context."

Asked if Prince Harry could be stripped of his spot in the line of succession, constitutional expert Iain MacMarthanne told Express.co.uk: "Something of a tradition has emerged relating to monarchical 'stories of the day'.

According to Mr MacMarthanne, removing Harry from the line of succession would create an "intolerable precedent" and that it was "easier said than done." © GETTYmeghan markle prince harry

Australian conservative social and political commentator Andrew Bolton wrote in the Herald Sun: "This is the couple who claim on their website to represent 'compassion in action', yet last week - as Philip lay in hospital - attacked his wife for removing the last of their royal patronages after waiting vainly for a year for them to return to a 'life of service' to their nation.
"'We can all live a life of service', sniped the runaway royals, 'service is universal'.
"Yet the service they offered Britain was an in-our-spare-moment kind that diminished the Royal Family and the notion of 'duty'."

Writing in the Mirror, journalist Darren Lewis said: "Anyone who watched The Oprah Winfrey Show during the Eighties and Nineties will know the Mississippi-born producer, author and actress is a woman trusted by great swathes of middle and working class America.
"A mother figure with the strong principles and quiet dignity of Meghan's own mum, Doria Ragland.
"To listen to the commentators pontificating on the strategy that Oprah will take is to know they have not watched a single one of her shows.
"Oprah is gentle, sensitive and understanding. She is no headline-chasing sensationalist.
"She has her own stories to tell about refusing to be silenced, fighting to ensure others have a voice and the unconscious bias to which Meghan has opened Prince Harry's eyes."
