No record of SA return submitted in account

I submitted my SA return on 29 November, which was successfully received by HMRC on the same day. However, it's been almost 2 weeks and I still could not see the return show up in my online account. Grateful if you could let me know whether this is the usual case and the possible reasons for the delay. Thank you very much.

Hi

If still not showing on your online account you will need to contact HMRC to review.
You can contact HMRC at Self Assessment: general enquiries

Thank you
