Honestly, my best advice would be for you all to move on with your lives and try your best to find an appropriate full-time job to qualify under CEC. We are lucky enough to be in Canada and don't have to worry about whatever work permits we're on expiring since we can always apply for a BOWP.
Best case scenario, we get our PRs soon. Worst case scenario we just apply under CEC and pay some extra fees. It sucks that we're stuck in such a situation, but always be grateful that you're not stuck abroad in your home country waiting anxiously for permission to land in Canada.
I'm not justifying IRCC's incompetence, all I'm saying is that be thankful for what you guys have since other outland applicants would kill to be in your place.
