More than 30 days I applied for N-400. No Biometrics appointment notice

[ramon1979]

My N-400 was received June 17th/16. Priority date June 17th/16. It has been more than 30 days and still no biometrics appointment notice in the mail yet.

There was a typo mistake on the zip code. They said they corrected.

I have friends who applied after me and they received their biometrics appointment in no time. Do I have to be worried? Can anyone share their experiences on this? please
