Once you go through the delivery survey, the button disappears, right?
The MyTesla page is back to the way it was yesterday, with no indication that they just told me that my car could be picked up in the next few weeks or that I just filled out their delivery questions (e.g., deliver/pickup, financing, etc.).
That is what I see. You should have gotten an email after submitting the delivery survey, and that email should contain your delivery window. If you didn't, you should probably send them an email ([email protected]) or call them.
