Hey there
This really confused me. I was playing some Pokémon shuffle and i got tired from it and closed the game.
I closed my 3ds's lid because i wanted to go and drink something.
After i came back and open the 3ds lid i saw the new software is installed window but my wifi switch was OFF. Pokémon Picross was there..
Can anyone explain why this happened?

You could have gotten it ahead of time, and it was just set to appear at the time it did.

Oh.. I got a notification about it before maybe that's why that happened.
But i got many notifications about other games but a thing like this never happened before
