Each day that passes I hate this fucking thing more.

Alright, /vp/, I need your help. I've been trading just fine with people I've had on my 3DS for a while but for some fucking reason, the friends I've added today don't show up in the plaza when we both get online. They don't see me either. I've tried refreshing the list, nothing. The friend codes are, I do see them online on the 3DS friend list, but not on the game. Can someone tell me what's going on?
