I think he meant where are you seeing the updated time frame, on the Apple Store app or another app, like Deliveries, for example?
On the Apple Store website and on the Deliveries app. Deliveries app seems to list the worst case scenario of 28th, however according to Apple it could be as early as the 23 rd- now that's interesting. It did not get shipped yet and still shows processing, but it did get updated about 30 min ago.
