Disconnecting AFTER Rivals Game

It’s been 2-3 times now in co-op rivals that I get a disconnect from ea servers after the game is finished and when menus usually load after the final whistle. I’m hard wired, 750mbs upload, 400 download, and sit at 20 ping as well as my co-op player. They end up getting the win but I get a loss. Please get this corrected as it’s not my internet rather a glitch.
