Are you expecting an RFIE or have you sent the response to them already?

I Sent the response, USCIS received 60 days ago, so far no update, it is in Nebraska

Was it for I-140 or I-485? I sent mine I-485 RFIE to another FO, they didn't acknowledge that they received it but case got approved after 110 days or so. If your RFIE mentioned about reaching out to them if you don't hear back from them within 60 days, I think you can raise a service request or chat with Emma.

It was for I-140, thank you

@A Gonz What was the RFIE about?

About the three prongs
