If I understood your question correctly,
In application section click your application for PR link will be "check full application status" on the page that you land see on the top against "Check the status, review the details and read messages for your application." there will be a link, click that it will take you the page where you will see the ADRs, if you have them attach scanned copy and submit. sometime it takes time for all this to appear on your profile, if its not there yet wait for sometime. I hope this helps.

Exactly my point. No message/place holder is showing in my profile since August 5th after linking my application online. My worry is that the deadline for the requested docs is October 10. My other worry is that am asked to submit a newly filled and signed background declaration form, am I suppose to fill the form, sign it and scan then attach the scanned form? I have already submitted these docs through webform (twice) but was told by a call centre agent yesterday that the requested documents are still pending. Very frustrating the way IRCC handles/process our applications, no clear direction/path or procedure watsoever!
