The press release was embargoed until 22:30 but @sussexroyal posted the news a few minutes before that (probably ensuring that they got the news out before the reporters were allowed to). I didn't see any UK reporters talk about that but Dutch reporter Rick Evers is really not happy about it:

A bit cheap they published it minutes before the ‘strict embargo’
They don’t respect the press, they just behave selfish

I never crap on her. I just notice they break their own rules. So that’s quite ridiculous.
When someone answered "The press doesn't respect them, so...", he answered "So: “let’s be childish”?"
Someone else said he was a lost soul because " These people are so full of hate their souls can only be lost." and he answered "The Sussexes? Yes, so it seems. It’s rude and selfish what they do."
He's getting hate from the stans but he doesn't seem to mind
