That doesn't stand up to logic
1. the people who applied in December 2020 online did not "receive an invitation" as far as posts on the forum suggest. They used the online link, yet some have now taken their oath of citizenship
2. people who applied in early January 2021 have received AOR
3. you're saying that Canada has taken money from people applying online and will now just, what, delete the applications? Because if you're saying 2021 applicants haven't received AOR because they weren't invited you're logically saying the applications have been received but ignored. If they haven't been formally received yet then, again logically, you don't yet know if they'll be accepted or not
Canada's citizenship application is not a lottery and you do a major disservice to the country you're hoping to become a citizenship of by even suggesting it.
The hysteria on this forum regarding online applications is getting worse and I assume is being fueled by trolls who are just fanning the flames for their own enjoyment. It's a new system, it's currently seeming to take longer except for those who applied early enough to be included in an apparent initial pilot scheme. That is all we know. Everything else is rumour and innuendo, and is detrimental to the provision of actual legit advice
