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.
May I ask why you are considering canceling the trade-in after 30 days and not just re-running it if the delivery goes past 30 days? I have even read in some threads that sometimes the value can go up based on the supply & demand of your vehicle and Tesla's algorithm.
I didn't want my order to get stuck again. Basically take that trade-in out of the order processing equation. I know trade-in value with Tesla is also less, but I also liked to convenience of just driving to the service center where I can pick up the car and driving a new car back. But if it's going to constantly caused an issue because their order process/system is not able to handle such request, might as well eliminate that issue all together.
