The Royal Family's website is yet to update the line of succession to reflect the arrival of Prince Harry and Meghan Markle's daughter Lilibet.
Its page includes information for fans across the world to keep up to date with the House of Windsor, from the latest Sovereign Grant funds, but also who is next in line to the throne.
But the site, has not updated the line of succession, despite Lilibet Diana Mountbatten-Windsor being born in the US six weeks ago.
Prince Harry's daughter Lilibet is eighth in line to the throne and like her brother Archie she does not have a royal title.
Harry and Meghan named Lilibet after the Queen's childhood nickname - but she will be known as Lili.
A statement from the couple's press secretary said: "It is with great joy that Prince Harry and Meghan, The Duke and Duchess of Sussex, welcome their daughter, Lilibet "Lili" Diana Mountbatten-Windsor, to the world.
"Lili was born on Friday, June 4 at 11.40am in the trusted care of the doctors and staff at Santa Barbara Cottage Hospital in Santa Barbara, California.
"She weighed 7lbs 11oz. Both mother and child are healthy and well, and settling in at home.
"Lili is named after her great-grandmother, Her Majesty The Queen, whose family nickname is Lilibet.
"Her middle name, Diana, was chosen to honour her beloved late grandmother, The Princess of Wales.
"This is the second child for the couple, who also have a two-year-old son named Archie Harrison Mountbatten-Windsor.
When Prince Louis, second son of Prince William and Kate Middleton was born, the website was updated 12 days after his arrival but this has still to be done for Lilibet.
And when Lilibet's older brother Archie was born in 2019, the site was changed to add him to the succession page after only 15 days.
It's been a year of change for the monarchy with three royal babies born and Princess Beatrice expecting a child later this autumn.
For Princess Eugenie, who welcomed her son August Philip Brooksbank in February this year, the website wasn't amended for 61 days to reflect his then-position as 11th in line to the throne.
The flurry of new arrivals has knocked a number of the Queen's children down the pecking order, with Prince Edward and Princess Anne seeing changes in their position.
The royal lineage order was also changed when Princess Ann's daughter Zara welcomed a baby boy.
Little Lucas Philip was born on the bathroom floor thanks to his speedy arrival, with dad Mike on hand to help with the delivery.
He is now 22nd in line to the throne, but if he had been born 10 years ago he would have overtaken his older sisters to go in at 20.
The Mirror understands the Royal Family's website is updated periodically.

Before Prince George's birth in 2013, the Queen changed the royal rules to state that female heirs wouldn't automatically lose their spots to a male heir born after them.
It comes as Harry and Meghan reportedly plan to have daughter Lilibet christened at Windsor Castle in a ceremony attended by the Queen, it is claimed.
The couple, who quit frontline royal duties for good last year, are said to be intent on having their youngest daughter christened in the same place her brother was.
If it goes ahead, it would be the first time Meghan has returned to the UK since 2019.
