So my series 7 shipped yesterday (Monday 10/11) morning, and for the first few hours I was able to access my invoice on my Apple.com order page (the "See Invoice" link only appears after an Apple product has shipped). However, I noticed that, contrary to previous orders of different products, the watch's serial number was not on the invoice. A few hours later, the invoice became unaccessible from that same link (I get an error message). And it's been like this every since early yesterday afternoon. Is anybody else able to see their invoice on the Apple.com order status page?
