I think the version in the workprint feels too much like –
“What’s the message?”
“It’s two lines from Palpatine.”
But it doesn’t imply that was the whole message. Taking the dialogue in the scene as a whole, it implies that they received some kind of First Order briefing message, of which the Palpatine recording was only part of. I’d say it’s much better than the theatrical version, where the message was basically “Palpatine’s back and he’s got an army of Death Stars, so you’d better hurry!”
