This is super weird. Its 10 months now and if they still don't see your application on the system, then something is wrong. Did you get a delivery confirmation from the courier when your application was delivered to IRCC? It might have got lost in transit.I have sent my Citizenship Application on October 28, 2020 to Regular Mail Address by Canada Post. I have not yet received Application of Receipt from IRCC. I tried reaching out to IRCC through WebMail and Phone however they are still unable to see my application updated in their system. Has anyone in this forum faced similar issue?
