Not according to the fine print in the app.
Among the things the fine print says in the LIMITS section
1. Related referral orders must be placed on or after September 10 2019
2. Referred vehicle orders must be delivered by October 1 2019 to qualify for awards
3. Orders must be placed through an active referral link to qualify
So, if you want this, you will need to cancel and order again with the person who referred you sending you a new referral link. I would NOT expect tesla to bend on this, regardless of what your owner advisor says. Plenty of people have been told "oh they will add it later" on these type of things only to find out that, no they wont add it later, when taking delivery.
