Child Benefit aproval

Hi, I added a child to my existing child benefit claim since 10 September 23 but I had no response about the claim since. I read on citizen advice website if you apply via the HMRC app you could get first payment after 3 days. When can expect response from HMRC? Thanks in advance.

Hi,

Please contact the Child Benefit team for advice:

Thank you.
