I think some of this could be true, but there were many reports like it and Meghan was reportedly prone to being difficult to work with, as well. Facts speak for themselves sometimes and Kate leaving the dress fitting for her daughter in tears, and multiple staff members leaving their employ, among other things, were evidence something wasn't right. Then, I think all the secretiveness with the baby really made people take notice. And yes, of course she has the right to have things her way. But this isn't a "normal"situation - the RF to a degree owe something to the people who love and support them, don't they? Even tossing a little bone to people like a timely official announcement or a quick picture, even if means one has to brush their teeth and hair and maybe put on a little makeup if they prefer, would've gone a long way to make people happy. Sure, she didn't HAVE to, but members of the RF generally understand theirs is a public role supported by the public purse and the tradeoff is that they have to sometimes do things they don't care to do. The Queen has set a great example for this over the years, as have other members of the RF. They live a lifestyle of priveledge and excess so a little wave to the public at special moments isn't a whole lot to ask, really.
As for the spat between the brothers, yes, I think you're spot on. William did seem to have concerns about Harry and his engagement to Meghan, and mentioned something to him about it, and it wasn't taken well. I don't know about you, but I've been in that type of situation where you're close to someone and they say you should be able to talk about anything, but when you mention concerns they sort of freak out and don't take it well. I think Willliam's concerns were well founded, but that did appear to be the start of a breakdown in their relationship, unfortunately. But William has a much different focus than Harry does, and is busy with a young family and many obligations, so it seems like they both moved on, albeit in different directions.
Charles, hmm. Was never a big fan BUT I'm not sure I'd say he has no emotional intelligence Stuffy? Yes, lol. But he did a decent job raising his boys and by all accounts was a very loving father. Camilla is said to be the person who brings Charles out of his shell and makes him laugh and enjoy some of the lighter moments of life. I was reading something just the other night that when Meghan first met him, she was taken with how warm and welcoming he was, and they got along very well. His work over the past two decades has been applauded and he seems to have redeemed himself in the eyes of the public since he was not too revered during the divorce from Diana amidst his ongoing love for and relationship with Camilla all during their marriage.
The Queen is a survivor and does care greatly about the Monarchy, it's her job and destiny and she's always taken it very seriously, but that goes back generations, too. She seems to me to be quite astute and not only aware of what's going on, but able to continue to be an active part of everything, as well - the talks this week with her son and grandsons being a good example of this. Harry must respect her opinions and authority if he got to the meetings early to discuss things privately with her before the official meeting started.
I think she's acutely aware of the problems going on in her family and is taking an active part in trying to solve them, all the while being cognizant of how the RF is perceived by the public and trying not to upset the apple cart any more than it already has been. I would imagine she's exasperated at having to deal with these types of problems when she has so many other responsibilities, especially at her age when the body doesn't always want to cooperate.
