"It wasn’t just William and Kate. A number of family members went over to see Meghan and Harry at Frogmore following the family Easter celebration at St George’s Chapel," a royal source tells ET.
Harry, 34, and Meghan, 37, moved into their new home earlier this month, a source previously told ET, and other outlets report that this is the first time the Duke and Duchess of Cambridge have visited the couple's new residence.
ET's source also notes that there has been concern about the distance between Harry and William as of late -- and the implication it could have on the monarchy -- but adds that they're "getting back on track."
As for the rumors that Harry and Meghan may be heading to Africa after the birth of Baby Sussex, the source says William is "completely supportive" of his brother's potential relocation.
"William has been completely supportive of Harry's potential Africa posting and has been an ally as he creates his own household," the source says. "The brothers are getting back on track and they’re in a better place than they were a few months ago."
Despite William and Kate's visit to Frogmore, a source told ET that there was an obvious distance between William and Harry during the Easter service, which Meghan did not attend because of her approaching due date.
Harry arrived at the church separately from William, 36, and Kate, 37, and stood at a distance from his brother when Queen Elizabeth II arrived. In the past, Harry has been seen walking in with his brother and Kate, who he feels is the sister he never had as a child, according to the source.
The source added that the brothers are at "different stages in their life" and are "no longer the boys" they once were.
On Thursday, however, Kate and Harry attended the ANZAC Day Service of Commemoration and Thanksgiving, which honors the sacrifices of Australian and New Zealand forces, at Westminster Abbey together. The pair looked to be in good spirits and were seen chatting and laughing.
William, meanwhile, was in New Zealand where he spent time with New Zealand Prime Minister Jacinda Ardern, met with police and ambulance staff and laid a wreath at Auckland War Memorial Museum.
