U will get in few days ... in some cases people get in 28 days.. but few ithers wait... disn't u way fee inline while applying... that maybe the reason of little delay... because they need to process the payment first..
I think we should wait... one of my friend got aor in 28 days .... he was also unable to link... once they will update their system we will able to link...
I think best option is open work permit after AOR.... if not yet then closed work permit with 204c letter.. here your employer needs to pay employer compliance fee check it on cic website
