In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

Citra doesn’t support online features that require connection to Nintendo servers. Using the citra multiplayer rooms or direct connection feature, citra can emulate local multiplayer options only. Meaning that you can trade and battle with people connected to the multiplayer room you’re in, by using the in-game Festival Plaza feature.
