I just applied a gift card to my existing One preorder, and it changed my estimated delivery date from Nov.22 to "unknown". I contacted Amazon, and they are going to attempt to change my delivery date back to Nov. 22, but it's not guaranteed. Unbelievable. I didn't cancel my order, I simply applied a gift card to my existing order. Apparently other people are having issues, too.
For reference, I pre ordered 15 mins after they started accepting them on June 10th.
