Hello, I was in the same position as you guys. I called the CIC agent yesterday (August 17th 2020) and they instructed me to decline the application. My profile is back to the state it was in just before I got the invite. My score is still on my profile and it states I meet the eligibility criteria for CEC and FSWP. I'm hoping I get picked in the next draw this week and will submit my application soon after. I already have all the documents gathered. Hope this helps those who are confused about declining their invitations.
