Newest version of Yuzu android (early access, playstore version) broke multiplayer.
The second Bluetooth controller is now also mapped as Player one, not as Player two. As there is no way to remap the controller this has bricked any multiplayer support.
In order for us to provide better support, we need to see the log generated by yuzu. This guide will walk you through how you can obtain the log file: Getting Log Files - yuzu
yuzu Can ask in the Android-support channel. They’ll look into issues soon enough 
A fair bit of changes were made.
I just installed discord. Unfortunately there is no android channel, please let the team know about this bug if you can. Cheers!
try reading the rules channel 
Bro I already went out of my way to create this account, then I created a discount account and installed the app, but I couldn’t find any channel to communicate with the team.
I already deinstalled the app, if you are there just let them know multiplayer in android is broken.
Cheers
It’s the main channel shown to you when you join. But sure I’ll let them know
