Insane! I had my iPad Pro, iPhone and Mac at the ready. My intention was to use the iPad to do the order, but at the last minute, I decided to refresh both the iPad and iPhone apps at the same time.
The iPhone app came up first, and I got my 256/White order in for Nov 3rd delivery. I'm in the UK - the store didn't come online for me until about 0804.
The iPad Pro app never came online!
I refreshed the iPhone a minute after ordering out of curiosity and orders slipped to 2-3 weeks!
