Yes - called and webchat. That is where the reason came from (extract below):

You will need to go to the airport to do this.
Us: How about the seat allocation?
Us: We would like to be sat together and with one aisle seat
Us: (we could have done that in economy months ago when we made our booking)
Them: The seats aren't available to select until you check in, as online check in is not available, the seats will need to be selected at the airport when you are checking in.
Them: In this instance, you cannot check in online for security reasons. It isn't something that can be prevented as a number of passengers are selected for these additional security checks at the airport.
