Much has been said regarding the shared relationship between the Fab Four, but thanks to a new advertisement starring Prince William, Kate Middleton, Prince Harry, and Meghan Markle, fans of the British royal family likely now have a renewed hope in terms of what the future holds. However, the debut was not entirely smooth as they did face an unexpected hurdle. What was it?

According to the Mirror, a website that was used to promote Every Mind Matters, a new mental health campaign that is a joint initiative from Public Health England (PHE) and the National Health Service (NHS), crashed after the advertisement made its TV debut at 8:45 p.m. on ITV, Channel 4, Five, and Sky.

Not only did the television spot seemingly signify that the Dukes and Duchesses may be looking to work together a bit more closely in the future, but it also made history as it is believed to be the first time that senior royals have taken part in something of this nature.

After only a few hours following the ad going live, the website met visitors with a short message that informed them that "something went wrong." Many believe the crash happened due to the overwhelming amount of traffic it received.

The Every Mind Matters website, which provides mental health resources, now seems to be running smoothly.

Working on issues pertaining to mental health is not a new point of interest for Prince Harry, as it was announced in April that he will be working in partnership with Oprah Winfrey on a new project aimed at reducing the stigma attached to speaking openly about the topic.

Due to the fact that the Cambridges and the Sussexes have reportedly faced some disagreements in the past, it was likely a welcome sight for royal watchers to see them reunite in this new way. In the past, Prince William has been said to be critical of the way in which Meghan and Harry are parenting Archie Harrison and the way they have chosen to lead.
