Please Fix this problem 343, build dedicated servers for halo mcc and fix all the issues campaign lag button delay and whole butch of other issues please read this and very one else’s comments on their issues.
I found uninstalling MCC and playing something else worked for me. I had to give up, a year of trying is plenty.
All i wanted to do was play Halo 4 big team battle exclusively on xbox one, nope, not possible.
Makes room for Halo 5. Bonus!
