Which center are you applying? Here is my sad story. I am in VSC. I did same thing. half year later, they didn't change it and denied my I485 based on NIW (I didn't response the RFE because I get approval on EB1). My attorney and I fight back but we were tole to send in a new I485. I did it and now I am still waiting. If you have both aproval, you might try to switch the link and will not hurt you.
