Same situation here. Ordered MYLR in early January (Metallic Gray, 19″ wheels, FSD), was offered a VIN in March but had to punt 30 days, the window reset to “Apr 15 – 29”, and then a couple days ago it jumped to “Oct 2022 – Jan 2023”. I’ve heard of a few other people in this situation, and for at least some of them the window eventually reset itself to “May 1 – May 15” or similar. I’m still waiting for mine to reset, hopefully soon!
