Finally got approval.
My case has been pending with DoS since Feb 2022. Filed a lawsuit which took about 1 month for all parties (USCIS and DOS) to be served. Once they got served, it took around 3 weeks to get FR from DoS. USCIS asked for an extension until Nov but ended up approving the case and sending me the final waiver within 2 weeks of FR from DoS.
I hired a lawyer and paid 5K. Good luck everybody
