Can't complete a match after yesterday's update!

Ugh, so frustrated. Ever since I updated yesterday I’ve tried to play about 10 games (arena and war zone).

I get disconnected every time and I’ve never been disconnected in halo 5 before this latest update. The game won’t be lagging at all then it will suddenly just go to the loading screen. Sometimes it will lag badly then boot me. Is there a fix or is anyone else experiencing this?

it can’t be my internet: 28 down 6 up

help!
