Timeline after Adjustment of status Interview ? (Marriage based)

[FaAh]

Hello good people,
My marriage based interview for adjustment of status took place on 25th June, 2022.
Dallas interview center. The immigration officer told that we would get a decision in one month.
But now it has been almost 3 months, and no news.
I filed for AoA on August 2021 (Green card spouse).

What are others' experience after the interview ? How long does it usually take after the interview ?
Thanks
