We filed a K3 a few weeks after our PD date (4/13/2023), but it didn't help us at all. Still took about a year for us to get approved. I don't know if it's cause our I130 was at Potomoc or not, or would have been same at any service center.
Interestingly, even though our I130 was approved a few days ago, the K3 is still open and looks untouched. So take that for whatever it's worth.
