Problem with Wonder Trade (Pokemon Moon)

Hi, I started playing Pokémon Moon a few days ago, and today I wanted to try Wonder Trade… and it didn’t work. Whenever I click on Wonder Trade or try to go online, the screen just goes black for a second and goes back to Festival Plaza.

I went online trying to find a solution, but nothing works so far. I don’t know what to do, cause I really wanna use Wonder Trade to try and fill out the pokedex… please help?

Operating System: Mac OSX 10.11.6
Citra: Nightly (latest version)
Game: Pokémon Moon

Any help is appreciated, thanks!!

Wonder Trade and other Internet connections use Nintendo Network, and we don’t connect to their servers.

The multiplayer feature (on Canary) only works with trading and battling trainers who are in your room (local multiplayer)
