Good news! I am the same configuration and one of the first people to register on Mar 31 as a non-owner. Let's hope we both get a call this week, although I don't trust my luck so much.I was definitely able to edit earlier this week. Tried the edit page again today and it just went back to my normal page. I haven’t had the edit button ever since I switched to no trade-in (was already cash). Just now I called Tesla to ask about my account and I was told I have been assigned a DSA and VIN, though she wouldn’t let me know what the number actually was. Hoping to get a call tomorrow and that my delivery doesn’t get scheduled for when I’m out of the country!
