I was asked for additional documents twice:Calling on any March inland applicant who had to submit additional proof of cohabitation/relationship documents. Wondering when you submitted these forms, and when (if) IRCC updated your application acknowledging receipt of the additional docs? We submitted ours Jan. 4th via webform but still no update on this.
ADR1: 30/12/20 ,uploaded same day using gckey.
Review of ADR1: 20/01/21 (and I got SA that same day).
ADR2: 20/01/21, uploaded same day using gckey.
Review of ADR2: 31/01/21 ( Got AIP that day too).
Then received COPR 01/02/21.
In both ADR instances, when I uploaded them on gckey, it showed up as uploaded on my gckey account. I called the immigration guys the next day after each upload, they confirmed that the documents were added to my file.
I would say call them to see if it has been added to your file.
PS: After uploading on gckey, I sent the documents through webform as back up
