Employment Based Greencard

I had my interview on 11/28/2018 and then the IO said hat she would approve my case later the same day, but I have not heard anything since then. As soon as I enter the room and take the oath, IO said she would not be able to approve my case on the spot as she was having an issue in her computer. A technician came in while I was being interviewed and suggested he would fix the computer at the end of the day.

Interview was then started with basic verification of the info from I-485, YES/No questions.
The only documents she was were passport, combo card and birth certificate.

I was asked to bring supplement J form in the interview notice. It was not submitted at the start because of concurrent filing of I-140 and I-485. She did not even ask for that during the interview.

At the end of the interview, she said all is well and she would approve my case as soon as her computer is fixed.

However I got a weird update on 11/30 night that my case is ready to be scheduled for an interview as of 11/23.

Has anyone else here have the same experience?
