Ok, so maybe I have been on here too long and have gotten WAYYYY to deep into finding the meaning in things on my Tesla account page on pc but I am 99% sure they changed the language under the little section:
Estimated delivery (Dont worry I was on the AU site every time)
I posted this a few weeks ago and copy and pasted it from my account:
Australian Model 3 Waiting Room
We will reach out to you to schedule your delivery date. Delivery time frame will be based on reservation date, order date, delivery location and vehicle configuration.
Now it reads:
Delivery timing will update based on configuration availability. We will reach out to schedule your delivery when your VIN is assigned.
