Hi, I just wanted to share my timeline because I also got an RFE. I just got my GC approved, they asked me for an RFE march 2022, I replied April 2022 and it changed to RFE received, after that I had no answer till last week march 31st 2023. They said case being actively reviewed but on the next day it said approved. So for me it was almost a year before they said something.
Hope the best and that your process goes the way you want
