Their Archewell website has been shut down, replaced by a simple black screen reading: “In loving memory of Her Majesty Queen Elizabeth II. 1926-2022.”
As a sign of respect to the Queen, users are unable to access any other parts of the website from the homepage.
Archewell was founded by the Duke and Duchess of Sussex and is used for charity work as well as their audio and film productions.
While the pair are currently in the UK, Harry didn’t manage to say a last goodbye to his grandmother.
Although he rushed to Balmoral in Scotland, he reportedly arrived too late with royal commentators calling it ‘very sad for him’.
Harry was scheduled to speak at the WellChild Awards in London on Friday night, but this has been cancelled.
King Charles breaks silence
The Royal Family’s official website has also been updated, after being made temporarily unavailable “while appropriate changes are made”.
A picture of a young Queen at her coronation is now shown on the front page, with text reading “Queen Elizabeth II 1926-2022.”
There is also a link for people to send a message of condolence to the royals, along with King Charles’ official statement following his mother’s death.
“The death of my beloved Mother, Her Majesty The Queen, is a moment of the greatest sadness for me and all members of my family," he begins.
“We mourn profoundly the passing of a cherished Sovereign and a much-loved Mother. I know her loss will be deeply felt throughout the country, the Realms and the Commonwealth, and by countless people around the world.
“During this period of mourning and change, my family and I will be comforted and sustained by our knowledge of the deep respect and deep affection in which the Queen was so widely held,” it reads.
