Even they claimed they put in all manpower to process CEC applications, things are really slow. My bf is an outland CEC applicant and he applied Sept 8, 2020 and he's still waiting. If you check out the CEC forums there are people who're still waiting, with AORs in June or July 2020... So fingers crossed... Now they're prioritizing Afghan refugees, so I expect more delays... I don't know where to complain but I have contacted my MP for help.His assistant did reach out and promise to at least run a check with IRCC concerning my bf's application status.
In short, IRCC is very messed up right now. Be patient and keep asking. That's the only way to go.
