Citizenship Ceremony - Dependant(Spouse) Application Update email not received

Dear All,

We've (My son, husband and me) applied for Naturalization under one application. But we've received Application update suggesting to book citizenship ceremony only for me (main candidate) and my son (dependant minor) but not for my husband (spouse).

But I've received survey email for my husband.

Is this normal or do anybody encountered the same issue? do I need to contact Home Office or council?

Do I need to wait till we receive my husband's application update before booking the ceremony?

Any inputs will be highly appreciated please.

Thanks in advance.

Received email for my husband after an hour and a half.

Thanks you.
