Prince Harry has never lost a case because of Andrew Green revealing his dyslexia.
Andrew Green is a British journalist who has written extensively about Prince Harry. In 2013, he published a book called "Harry: Conversations with the Prince," in which he discussed Harry's dyslexia. Green has also written articles about Harry's dyslexia for several newspapers and magazines.
However, there is no evidence that Green's reporting on Harry's dyslexia has ever resulted in Harry losing a case. In fact, Harry has never spoken publicly about his dyslexia, and it is not clear how much he knows about Green's reporting.
The claim that Harry lost a case because of Green's reporting is likely based on a misunderstanding of the facts. In 2013, Harry was involved in a legal case against the Mail on Sunday newspaper. The newspaper had published an article that Harry claimed was defamatory. However, the case was settled out of court, and the terms of the settlement have never been made public.
It is possible that Green's reporting on Harry's dyslexia played a role in the settlement of the case. However, there is no evidence that Harry lost the case because of Green's reporting.
