What would happen if after you submit a second application, you receive AOR for the first one ? Would IRCC put your first application on hold till you withdraw the second one ? Could it lead to more delays ? These are the questions you should be asking. I think as long as there are others on this forum who applied around the same time as you and are also still waiting, it's better to wait it out than submit another application. High chance that it's just buried under a pile of other applications.I said the same thing to myself last week however nothing happened... I don't think one has much to lose if re-submitting now. Strongly advise preparing documents this weekend and submitting on Monday.
Meantime doesn't hurt to start prepping another application package.
I know it sucks. I was super frustrated myself, to the point that I was spamming their facebook and twitter for answers. After almost 6 weeks of wait, I did finally get the AOR.
