I CANT FINISH MULTIPLAYER ONLINE MATCHES

the multiplayer online mode always go with delay and lag , and in few minutes is disconnected and out from match , this is constantly , only few times i finish the game in multiplayer online

That happened to me when I used my pc: it seemed like cross platform matches ( from my pc ) did not work, while cross platform matches ( from my xbox ) did. I do not know if this is related to some connection/router or pc issue, or it is just some sort of bug
