Equally confused here as this is exactly what’s happening with my order. I tried to get clarification this morning but the sales rep I spoke with was combatively unhelpful, unfortunately.Still not sure how to best update my saga... but my 'replacement order' from 11/27 that replaced my original order from 11/12 (Apple did it, not me) finally has some movement and has a 'departed from facility status' which is the first update since 11/20. This is the original tracking number I received back on 11/18 and the UPS app says its on track to schedule by end of day 12/08. Apple Store app still shows 'preparing to ship' and a 12/22 expected ship date.
At this point I would have just taken the long Shanghai delay. The weirdness with my order number makes me nervous on when I'll actually receive the laptop.
