That's how I interpret the Palace's news release. The Sussexes had a "tea visit" and that's all. I would bet maybe an hour and a half or two hours at the most. It could have been only an hour with Camilla present and I'll bet staff were "around".
As the article stated yesterday, this entire visit was about money (as always), for themselves and Invictus. Oh, I'm sorry, I'm writing about the same the same goal. Invictus money is Harry and Meghan's. It wouldn't surprise me that Harry started whining and demanding the minute he crossed the doorstep.
