The late Queen Elizabeth had a 'uneasy' relationship with the Sussexes, which is well known. However, a royal specialist responded to the issue of how things came to this position.
According to biographer Ingrid Seward, the rift occurred during the couple's 2018 wedding.
She said that the late Queen was angered by the royal prince's "high-handed attitude."
According to the Daily Mail, fissures in their relationship began to emerge following the wedding.
One such episode was Harry's rage at the queen's dresser, Angela Kelly, for failing to satisfy the last-minute requirement of preparing Meghan Markle's bridal tiara.
The late queen intervened to settle the scene, but she was not pleased with the now-father-of-two's actions.
In addition, the Suits actress' decision to wear a white dress to her wedding with Harry, despite the fact that she is divorced, irritated the royal family.
In other developments, Tom Bower, another royal specialist, told The Mirror that the royal couple may face challenges in the future in the United States.
"If history is to be an indicator of their future together, the royal couple may face more bumps in the road - but they will do so united, for better or for worse," he told reporters.
He then added, "I'd be very surprised if she didn't stay loyal to Harry; it would be completely contrary to everything we've seen of her."
"It is hard to know exactly what the future holds. Aside from Harry publishing another book or Meghan writing about her experiences, they must find their purpose," the analyst noted.
"The actual difficulty for them is what does Harry do?" Tom said, adding, "He's 40, has no formal function, and has many adversaries. Being away from his family creates a void, which he must fill in California with Meghan.
In May 2018, Harry and Meghan exchanged vows at St George's Chapel in Windsor.
