Is Apple going to fix gamecenter

ive updated to newest iOS and now gamecenter does not work anymore. Just a white screen and can't play certain games. Now I guess my new iPhone 6S plus is just now a telephone and MP3 player. This problem has lasted 3 months. I can't log off and log back on because phone freezes and just shows a white screen in gamecenter. Is there a fix or soon to be a update for this?
