It's fair to say that when the trailer for Prince Harry and Meghan Markle's Netflix documentary was released on Thursday, it hit a nerve.

It was great enough to see it actually come to fruition, but it's the timing that has commentators talking.

This first look of Harry and Meghan was released during Prince William and Kate's long-awaited visit to the United States. Of course, it was Netflix's decision to release the trailer, but many commentators seem to think that the Duke and Duchess of Sussex could have at least had a little say in its timing.

In the trailer, Harry states that he "had to do everything he could to protect his family," a statement that has been disputed by royal expert Kinsey Schofield.

"Harry says it was to protect his family, yet he stirs the pot while the Prince and Princess of Wales are thousands of miles away from their children. Irresponsible," Scofield tweeted.

"All Princess Catherine would want to do is hold her baby ...... Instead she is dodging a grenade from her brother-in-law."

"She is not a baby.

The specific issue at this juncture is not simply the Sussex versus Welsh issue, but the emphasis of William and Kate's journey on environmental support, which Harry and Meghan are also working on.

"For them to do this on the first or second day of the Crown Prince and Princess's trip to the United States for the Earthshot Prize really shows how much they wanted to take advantage of that publicity," royal expert Jonathan Sacerdoti once said in Us Weekly magazine.

"It's possible.

"It means they will do whatever it takes to get as much publicity as possible. They will jump on his own brother's trip to promote these environmental awards to steal that limelight and get more attention."

The "Us Weekly" also reported that "the most important thing is to get the publicity for these environmental awards, and that's what they're doing.

Oh, brother.
