Mcc Co op lag

I just want to play co op with my brother but whoever isn’t host gets extremely unplayable lag it’s insanely frustrating and I wouldn’t be bothered by the matchmaking issues if him and I could just co op together I’ve seen forums all over the internet that mention this problem if this isn’t fixed soon then I demand a refund on this game I didn’t buy it to play by myself and I only bought and x1 to play this game please fix this 343 halo holds the highest sentimental value of any game for me and my bro I have faith in you guys

Which Halo? Ive played the crap outta H2A co-op over XBL and had NO lag whatsoever. Host or not.

Ce and h2a but I’ve seen others comment the same thing as you some have this issue and others don’t
