Apple shipped my phone yesterday (sunday morning) and on their website it say I'm supposed to receive it on october 6, but when I click the link "track order" the ups site still says the tracking number is incorrect and can't be found. Normal after almost 2 days?
i think you have to forget about Sunday for pickup so really it has just been today. Very possible it will show up in the system overnight as it’s most probably being shipped from China. Once they get picked up they can move very fast. I wouldn’t be concerned unless you don‘t see it in the UPS system by tomorrow afternoon.
Apple is rarely wrong about the receiving date. If wrong it’s usually in your favor.
