I had a similar situation. 7 days nothing and what I was told by the SA was that the trade-in was stuck in process for some reason and he contacted the trade-in department and got it resolved it went through right away. SA also said because it was stuck my RN was also stuck so it was like the order never went through due to the trade in situation even though my trade-in was in good condition. So my advise is if you haven't heard in 7 days or more, you need to contact them to ensure your reservation is not also in stuck. Trade-in is no big deal, getting the order stuck is much more of an issue. Reason trade in is no big deal is because it's only good for 30 days once approved, and your Tesla might not be ready by 30 days. I almost took the trade-in off but decided to keep it but if it expires before my Tesla is ready, I'm ready to cancel the trade-in and bring it to a local place like Carmax.
