Regarding Naturalisation application

Hi all,

I submitted Naturalisation applications of myself along with my 2 children who were not born in this country in November.
Yesterday we received 2 letters containing approval letters and certificates of naturalisation for both my kids.
Naturalisation certificates dated 29th March and approval letters dated 1st April. I still haven't received any email or letter for my application. I found this very strange as we all applied together but received no correspondence for me. Is this something normal? Is there a possibility that my application was not approved?

Even if you all apply together, every person is still assessed individually, there's no family or dependent concept for naturalisation and registration.
Your approval may arrive in days or weeks, hopefully not in months.

Alright, thank you
