For those still waiting.
preordered around 240AM CST, had to go through VZ online CS to order it as I could not remember my PIN and was subsequently locked out of my own account. ordered the 256gb gold XS max.
Had the status processing this whole time with ETA 9/21. Then just now got a text saying my order was received, logged back into VZ website to check status, and the ETA disappeared, so i chatted with the VZ CS online rep, and they reaffirmed my phone was already shipped and will get it at the original quoted 9/21. Still havent been charged either. (ordered the installment plan, not the bulk payment). account is on autopay.
So bottom line: the website may not be completely up to date, let alone accurate, most cases the VZ CS reps are useless, in my case they were helpful.
edit: just got charged.
