Royal fans were left scratching their heads after Prince Archie's official profile on the Royal Family website mysteriously vanished before reappearing.
But despite now being restored, a glaring error still persists on the page that was recently updated to reflect Prince Harry and Meghan Markle's son's new title.
On his official page, there is the first-ever public photo of Archie, showing him being cradled by dad Harry and mum Meghan just days after his birth at Windsor Castle.
His profile reads: "Prince Archie of Sussex was born at 05:26 on Monday 6th May."
It then goes on to describe him as the first child of the Duke and Duchess of Sussex - but incorrectly states he is seventh in line to the throne.
Although this was correct at the time of his birth, Archie is now sixth in line to the throne following the death of his great-grandmother the Queen.
In fact, on the site's line of succession page, he is correctly listed as being sixth in line along with his new title Prince Archie of Sussex.
And it seems Archie's profile is not the only one not to have been fully updated recently.
Prince George is still listed on his profile page as being third in line to the throne, despite now being second, Princess Charlotte's profile says she is fourth instead of third, while Prince Louis' profile describes him as fifth rather than fourth.
Harry and Meghan's youngest child Princess Lilibet does not have a profile page on the site.
However, it does seem that Buckingham Palace is in the process of extensively updating the site and a message at the top of each page reads: "Some information on this website may be out-of-date following the death of Queen Elizabeth."
It emerged earlier this month that Harry and Meghan had started using titles for their children Archie and Lilibet.
They became a prince and princess on the accession of their grandfather the King six months ago, but the Sussexes publicly used Lili’s title for the first time earlier this month when announcing their daughter's christening.
Archie and Lili are now listed on royal.uk's line of succession page as Prince Archie of Sussex and Princess Lilibet of Sussex.
Previously they were Master Archie Mountbatten-Windsor and Miss Lilibet Mountbatten-Windsor.
A spokesperson for Harry and Meghan said the decision to use the titles had been "settled for some time."
"The children's titles have been a birthright since their grandfather became monarch.

"This matter has been settled for some time in alignment with Buckingham Palace," the spokesperson said.
Lili, who is 21 months old, was christened in an intimate ceremony at the Sussexes’ family home in California, watched by her grandmother Doria Ragland and celebrity godfather Tyler Perry.
The King, the Queen Consort and the Prince and Princess of Wales were reportedly invited but did not attend.
