Update
So, since Feb 22 submission, I have received an RFE and sent the documents immediately. In June, I got my expedited EAD. Ever since June, I had two different dates by “RFE evidence received” - the above said received in March and the other said received in June. And today, after six months from when they last looked exactly, I received an email from USCIS that my 485 was approved. No interview! I hope things start moving for the February filers!
