Choose following, when you are submitting the form relating to QSW.
1. complaint
2. Policy and legislation
3. immigration policy.
Folks, this is the right time to submit feedbacks, because there is a parliamentary comitee negotiating new policies with IRCC and the members of that comitee can really use our help or feedback to push IRCC officials to introduce new legislation or policies on paper files getting dust since couple of years.
Edit: It takes only 5 minutes to write a complaint and there are zero consequences on your immigration file. Because it is understandable to file a complaint after waiting 17 months without "official AOR" and living in precarity and anxiety of getting your file returned for a missing document or signature with expired CSQ.
