N-400 citizenship process has not progressed since 8/9/2016 SF office

[bayareasearch]

Applied 3 months before 5 year completion

7/27/16 N-400 application accepted

7/29/16 Received notice to go for Biometric appointment in Oakland,CA

8/19/16 Went for Biometrics appointment

Nothing since then!!!!

I have been legally separated for 3 years now and had received my Green Card through my ex husband. Could this be the reason for delay???

I have checked the processing time for SF and it should June 2016. But I also friends who have received their citizenship months back!

I called the help number but nothing helped.
