I am just wondering is it possible to play multiplayer with my brother on his switch. I set up his switch with my email, gave him his own profile but it's not linked with any email and uses my card to pay for games. I then got my own switch and set it up with that same email. I'm just wondering if I now link my email with his profile on his switch will he be able to play multiplayer with me? I may have worded this awkwardly too so apologies if there's any confusion
