response from USCIS about N-400 delay

I have emailed USCIS by using my online account and I got a quick response from them but it seems like an electronic response. I was asking if there is any issue in my case after my wife received the interview but I did not receive any update yet. here what I got ..... please let me know if anybody here got a positive result after this email.

I got similar to this but about final approval after interview, my inquiry was about delay for ceremony letter and my online status stuck on "we scheduled your interview" and there is no estimate time for my case ! waiting for 120 days pass from my examination.

Thank you for your inquiry dated February 24, 2020.

USCIS systems indicate that you appeared for your naturalization interview on December 23, 2019. If final approval is granted, you will be notified of when and where to report for your naturalization ceremony.
