Hi Guys,
I already sent my online application on March.25.2021 and still waiting for AOR, today I called IRCC and talked to them and he updated my profile, but he told me your application not uploaded to the system yet, but no worries it takes time and you have just to wait for AOR, and about the randomly selected he described when your online application submitted without any problem and you received the automated email from us(Not AOR) it means you are eligible and randomly selected.
Finally, he told me they are working on an online system to process the application quicker from the paper base.
