AVP Purchasing experience should be improved
I understand that it takes time to manufacture the lens for the APV.
However, imagine that you, as a customer, spent $4000 to purchase something you love and you cannot use it until a week later. It's really bad for the customer experience and I am shocked that Apple didn't do anything about it.
For demo purposes, Apple did have some backup lens.
Apple could actually lend or loan the lens temporarily to the customer who ordered the lens but has yet to receive it. That would have helped a lot, and probably this business model can earn the demo material back.
