Thank you !!!!!Did you try registering on new tracker? Since I put myself as a representative for my spouse, I was able to register myself on GCKey before I received AOR. Also if you do try to register on GCKey then put "2" under number of applicants even if it's only one. I hope it works for you.
I submitted application through immigration consultant. I think he is the representative. Will ask him to register in new tracker.
