UoM (Manchester) No Portfolio Email Yet

My other 4 choices have already emailed me asking for my portfolio for architecture which is fine, however UoM (the university I want to go to) hasn't asked for my portfolio yet. I sent off my UCAS during the middle of December and its already February and I'm getting slightly nervous. Should I be worried or not? Is this normal?

Have you had any acknowledgement of your application from Manchester at all? Have you checked you junk email?

I have had an acknowledgment email when I initially sent my UCAS in December saying they’re looking at it but I’ve yet to receive an email asking for my portfolio while all my other universities have asked already. I checked spam and junk and no portfolio email.
