As another data point, my stays have been crediting but I had a couple of stays in a row that didn't post. I just uploaded them to the website on Wednesday to get credit but didn't send them to my ambassador. I received an email today from my ambassador telling me that she had credited them to my account and telling me I can just email any to her in the future. That's about a 36 hour turn around and interesting that an upload to the website would get referred to her.
