I also have a collection of these celebratory confetti messages. I was thinking of trading them like hockey cards.
In the app, they seem to appear after an app update and/or when I login.....but who knows really.

I seem to have captured the screen shot during the "higher volume confetti phase"




I really like the desktop version because it's more colourful and the confetti goes everywhere with no clean up required.







At first I was amused, but now I think that if AC wants to keep congratulating me for achieving Aeroplan SUPER ELITE, they should offer some 🎂 or 🍫 to go along with the confetti 🎉🎉🎉. LOL
