The Linleys, Chattos, and Princess Anne were definitely present to support Charles. It's said that's because Princess Anne was present at Charles' original investiture ceremony, as was Princess Margaret, who is now represented by her children.
Below are engaging still photos of the royals at the reception; in one set of pictures, Princess Anne is seen having a lighthearted conversation with the Sussexes, whom she appears to get along with well; Meghan is seen in a wide-legged stance, surely feeling her pregnancy in these latter weeks:
Notice the interesting family dynamic seen in the Royal Channel Family video
@Dman posted earlier (post #242); see at about 2:03, where Prince Charles is talking with Harry and Meghan before joining the Queen to walk in and view the investiture exhibit. Charles actually turns back and continues speaking with Meghan, which is further evidence to me of their close relationship, forged during the royal wedding planning and immediate aftermath when H&M postponed their honeymoon to help celebrate Charles' 70th year at the BP garden party. By this point, I think it's clear that Charles is like a surrogate father as well as a father-in-law to Meghan. The Queen's equerry appears to have a fond relationship with the Sussexes too, as they move around and converse comfortably together in the background of that video.
Here's a
Town and Country article about Princess Anne attending the investiture reception. The report explains why Andrew and Edward weren't present. The Linleys and Chattos were surely attending as representatives of Princess Margaret. Includes more pictures of Princess Anne chatting amiably with the Sussexes:

Just to briefly add to the discussion about British royal family roles: This is a family who have learned the importance of what 'one for all and all for one' truly means. By this point, I think this new generation knows and understands what their roles are in this family. The good thing is that both the Cambridges' and the Sussexes' personalities are ideally suited to the roles they are expected to play. Any adjustments that have had to be made with a new family member joining the firm have already occurred. Meghan is smart, savvy, hard-working, articulate, gracious and eager to fit in, which she has accomplished exceedingly well. The royals know exactly what an asset Meghan has been to the family and what a gem and indispensable boon she has been to Harry. Prince Charles has been quoted as saying:
"Meghan is the best thing to have happened to Harry." And Charles is known to call Meghan, 'Tungsten.' It was also reported that after the Sussexes' Morocco tour, HM the Queen was so impressed, she wrote a rare letter of thanks to Meghan for her hard work ethic.
I also think that Meghan and Kate are quite cordial with each other and comfortable in their respective roles. If there were previously any tensions between them specifically, they certainly appear to be on an even keel now:

As has been reported, it's probably likely that Harry and William have recently experienced some personal tensions, which will surely be worked out over time. But I doubt their tensions have much to do with not knowing what their respective roles are in the family. Any tensions are likely more do to with natural growing pains that occur between siblings. The Sussexes are very important to the main family unit, and they will continue doing work that will reflect well on the British monarchy, and help enhance Britain's and the royal family's image around the world, which only adds to and takes nothing away from any of the major royals who will inherit the throne.
And now for some humor, which is all in good-spirited fun:
