Prince Harry and Meghan Markle had hoped to make amends with the Queen next year, but were never able to do so, according to The Sun.
But following Her Majesty's state funeral, which forced the couple to make a swift return to the family, the Sussexes hope to improve relations with their estranged relatives, the Mail reports.
PR and communication experts suggested the pair had been trying to create their own narrative, clearly referencing their string of podcasts, interviews, Netflix series and Harry's promised biography.
Speaking on the Netflix series, an insider told The Telegraph: 'This is about where they’ve come from, what they’ve been through and where they are.
"I think it will explain a lot about the decisions they’ve had to make and how they’ve ended up here."
The fly-on the-wall series, which is part of an $100million deal with the TV giant, was expected to release later this year.
But the couple has reportedly asked Netflix bosses for it to be pushed back to 2023 in light of the Queen's death.
In September, it was reported that Harry had also pleaded with his publisher to U-turn on a number of critical claims about his family, written within his memoir, over fears they would not be well received in light of recent events.
It had been signed off ready for an expected autumn release, but the Duke – who is writing the book as part of a near £40million three-title deal – allegedly asked to make some significant alterations.
A source told Mail Online: "Harry has thrown a spanner in the works.
"He is keen for refinements in the light of the Queen's death, her funeral and his father Charles taking the throne.
"There may be things in the book which might not look so good if they come out so soon after these events.
"He wants sections changed now. It's not a total rewrite by any means. He desperately wants to make changes. But it might be too late."
Publisher Penguin Random House had already demanded a rewrite after the first draft was deemed 'too touchy-feely', The Mail on Sunday wrote last month.
All this comes as Harry and Meghan faced a series of explosive claims about their own lives in a tell-all book - but it remains unclear whether Prince Harry will address any of these in his memoir.
Billed as an 'accurate and wholly truthful' account of his life, American sources suggested that publishers will want it on the shelves in time for Thanksgiving, but no official release date has been given.
In a statement announcing the global publishing deal, Penguin Random House described it as "an intimate and heartfelt memoir", promising that "Prince Harry will offer an honest and captivating personal portrait".
The publisher added that the book would cover Harry's "lifetime in the public eye from childhood to the present day, including his dedication to service, the military duty that twice took him to the front lines of Afghanistan, and the joy he has found in being a husband and father".
The Sussexes have spent more time with the Royal Family since the Queen's death than at any time since Megxit over two and half years ago.
They were already in the UK for non-Royal charity events when Her Majesty died, the day before they were due to fly home to Montecito, California.
In the aftermath of his grandmother's death, Harry struck a fragile truce with his brother William – appearing together for a walkabout among well-wishers in Windsor following the funeral.
