It failed for me in Smash For 3ds, Mariokart 7, Mario 3d land, Street pass Mii Plaza, and Mario Maker 3ds. However after rebooting 2 times, the street pass for Mii Plaza seemed to show up
Having an issue on Ver 0.2.2 where it just doesn't update the street pass data. I get the green notification light on games, but going into them there is no registered tags
