How long to process I-800A????

Our SW said that things are moving slowly across the whole Us as far as I800A's. They are rejecting many of the homestudy's for revisions. We have been waiting 11 wks tomorrow (77days) and our homestudy has not been sent back yet for changes (let's hope ours is ok). Our SW received notice 3 weeks ago that we would be contacted soon for an appt-whatever soon means to them???
