Adjustment of Status - I-485

Hi everyone,

I have been following this forum for a while now and I would like to thank all for sharing your experience, it is really helpful. Here is my timeline so far:

4/15/16 Package arrived at Chicago lockbox (I-765, I-130, I-485)
4/22/16 Check was cashed
5/07/16 Received Biometrics Notice for appointment on 5/24/16
5/21/16 RFE for I-864 received
5/24/16 Biometrics Done
6/07/16 RFE response received by USCIS
6/07/16 I-765 expedite request submitted
6/18/16 I-765 expedite request completed and New Card is being Produced
6/28/16 EAD received in mail

I-485 still showing "RFE response received". My question is, I received my EAD without getting a single NOA1 or NOA2 for all documents ((I-765, I-130, I-485). Is this normal, shall I be worried? Also, how long does USCIS take to schedule an interview after RFE response received?

Thank you everyone!
