A source told The Telegraph Kate is focused on healing royal rifts and doesn’t care about issues surrounding the matter.
They said: “The Duchess hasn’t said much about Oprah at all.
“I think the bridesmaids’ dress comments were the least of anyone’s worries.
“And she’s not really the type to get het up about these sorts of things.
“She’s just trying to help to bring the family back together and alleviate her husband’s stress and sadness.”
The feud between the Duchesses of Cambridge and Sussex allegedly began over whether bridesmaids for Harry and Meghan’s wedding should follow royal protocol by wearing tights.
Royal sources said the “stressful” situation left Kate in tears.
During the Oprah interview, Meghan Markle said the confrontation had “really hurt my feelings” and marked a “turning point” in their relationship.

Kate’s uncle, Gary Goldsmith, described her as a “brilliant arbiter and peacemaker” who was trying hard to bring the family together again.
He told Closer magazine: “If Harry doesn’t get a grip and stop this self-indulgent episode, there will soon be no common ground or relationship to rebuild.
“But if anyone can bring peace to the royals, Kate can. Kate is a brilliant arbiter and peacemaker.
“Every bone in her body is about making friends and doing the best she can… she’s trying to mediate.”
