If u can't access it still, call the CIC Call Centre 1-888-242-2100 and speak to an agent. Ask them for help with your ecas.
Hopefully they can help to get it activated for you.
You already have AOR so your app is definitely under processing, don't worry.
You can always ask your local MP's office for help as well.
