Yep same thing is happening to me. Not surprised though, EA just copy and pastes this game mode to each new madden game that comes out. Showdown has had the same bugs for the last 3 years. Not earning any XP or RP either, at one point it told me I completed 3/5 placement games when I had already played over 20. Now it doesn't even bother giving me a summary of the match, and it just boots me back to the lobby, same as you. Such a joke a complete joke. I switched from my QB to my Cornerback to see if anything would change (of course it wouldn't). EA is a complete joke of an organization.
