Do you have a trade in? If so, take it off your profile entirely until you actually get a VIN. All sorts of ****ery can happen with trade ins causing the profile completion date to be reset in the system. Pretty sure that trade ins are the root cause of 99% of the extreme delays that some people have experienced.
Fortunately, waiting on submitting the trade in will likely be to most people's benefit right now anyway, as the chip shortage is probably going to get worse over the next few months and used car prices will just keep climbing. The later you get that trade in offer, the better. (for now at least)
