Locks up game every time, but only multiplayer. Single player is OK. Went into router and opened all ports. Reset router, held xbone button down for 15 secs to reload that. I once got an error on testing multiplayer but couldn't get the error again. NAT is open. All other games/apps work online fine. It's only Madden and only my Xbone version. Ive uninstalled and reinstalled, deleted all associated files and still the same issue.
