Harry is no longer his 'shine'. The family removes the title from the father
Harry no longer has a title. HRH, i.e. 'his highness' will no longer be used in reference to Harry.
The family has made updates on the official website.
Now he is just the Duke of Sussex.
The site was careful to remove Harry's title, while it still features Queen Elizabeth and Charles remains a prince.
Remember Harry and Meghan have left the family to continue a life as non-royals. So far they have been engaged in various projects on Netflix.
