This is the same issue I mentioned earlier in this post except mine was under the same email address but they had two accounts with that same email address: one under Mike and another under Michael. They said it would take 2 - 3 business days to update. So far I'm still showing 2019 delivery dates for all builds. What's your reservation date and what are you showing for delivery dates?
I should add that the agent I spoke to today told me that in addition to going West Coast to East coast, Employees first to non-employees and owners to non-owners, she stated that the line could be getting even shorter as they're seeing more people that want to wait for the cheaper car. She noted that a lot of employees were opting for the cheaper car as well. So if you're willing to take first available and you're an owner, things are looking pretty good for 2017.
