From the BBC
“Prince Harry and Meghan Markle remain in their home in Montecito, California. The fires are burning some distance from there.
The BBC understands the Duke and Duchess of Sussex have been truly shocked by the situation and are keeping a close eye on developments.”
This is what I mean. They are close to a big event happening, so they are expected as Royals to say something.
This is why the celeb stuff doesn’t work. It’s not bad timing, it’s trying to launch yourself as a celeb butting against this. If they only undertook charitable efforts etc, the issue of the fires themselves, wouldn’t cause an issue for Meghan. But because she is Royal, she is expected to comment on such issues but then that scuppers her efforts as a celeb, who wouldn't need to talk about these things and be asked for comment.
This why it looks like bad timing but it isn’t. There will always be big events happening in the world that Royals (who keep themselves in the public eye) will be expected to comment on.
She can’t do both- be a Royal and Celeb and expect smooth sailing. She will always be curtailed by world events while maintaining dual roles. Just like when the Queen died and she had to delay the podcasts.
