When my sponsor called IRCC to ask for help to link our app, the officer has mentioned exactly the same answer you have told me. Most make same mistake by entering 1 instead of 2. Thanks again.
They can only give status of application from her side, sponsor. They have told her that our app is in Mississauga office for Sponsor eligibility review progress.
Update: my sponsor called CIC, we are in SA eligibility review process (Mississauga office). I can't call to check mine as I am working right now o_O.
