Menu and campaign issues

A few issues I am noticing.
First-When in multiplayer/warzone the LB and RB to switch to social or customer game does not work. I can use RB from social game to warzone but once in warzone it stops working.
Second-in Campaign the cut scenes sometimes do not load and get stuck at a black screen. Extremely annoying when playing on Legendary since you have to just skip it by, backing out and starting the next mission from the menu. Missing the end mission cut scene is…unacceptable with a campaign game.

I have had this game since launch but just started playing this past December 2016. Surely there is a fix or and update for this by now.

You are exactly right.
