Received notice of biometrics reuse on the same day my application was filed online.
Just had my interview last week--IO was congenial but not overly friendly. I was done with the interview in like 5 minutes. My status updated to "Oath Ceremony Will Be Scheduled" right after I left USCIS. That night, it updated again to "Oath Ceremony Notice Was Mailed."
My oath ceremony will be on the first week of September
