Prince Harry and Meghan Markle were frustrated when the Buckingham Palace did not immediately update their children's royal titles on the official website.
Although the names of Prince Archie and Princess Lilibet have now been changed on the website after a day of announcement that they will be using their HRH titles, the Duke and Duchess of Sussex were reportedly annoyed at the delay.
A source told The Mirror that it was no secret among their friends that Harry and Meghan were frustrated with the palace's failure to recognize their children's elevated status on the website.
The insider also added that their frustration was compounded by the fact that the titles of the Prince and Princess of Wales and their children were swiftly changed after the Queen's death in September.
Omid Scobie, a close friend of Harry and Meghan, confirmed on Twitter that Princess Lilibet Diana was christened on March 3, and also claimed that King Charles, Queen Consort Camilla, Prince William, and Princess Kate were invited but did not attend the ceremony.
