The online on the nintendo switch nearly working 

Can't log to my Microsoft account very well and can't play local or onlinw multiplayer 

I'm just trying to play with my brother at home and we both have our own switch and copies of the game 

But nothing works and we can't even play together 

It worked once but that's it and after 3 hours of trying and ita very frustrating and just makes me delete the game and never play
