Can't change sensitivity in master chief collection.

I just booted up Master Chief Collection on my Xbox for the 1st time in almost 2 years and I’m having the same issue. I’ve never had to change my setting again after configuring them for the 1st time after starting the game in 2015 and they were fine last time I played it. But now it turns so fast I can’t even play. I’ve turned all in game sensitivity settings to lowest setting with no effect. I rebooted the game and have tried each Halo game, and the only one that isn’t doing it is Halo 2. Not sure what’s going on with the game. My sensitivity was fine in a different 1st person game I was playing just yesterday.

I'm having the same issue on console, the sensitivity settings don't change anything and I'm left playing as a human vortex. It's very odd.

I am having the same sensitivity issue! But it is only when I am playing on cloud gaming, on the console I don't have an issue.

Hopefully 343 can fix this soon, it is super frustrating.

I was the one who submitted the ticket with this issue after the update I’m still having trouble when launching the game on both PC, Cloud gaming, and Xbox. Halo 3 is unplayable, halo CE, halo 3 ODST, Halo 4, and halo reach. Except halo 2 where the look sensitivity is normal but as for the other campaigns and or multiplayer it’s still unplayable.

There was a recent update to the MCC so it's possible something got broken (the Updates always break something)..even more so given they released a hotfix a day or two later...can't find out what the hotfix was for though so it may be unrelated.

Can't find anything on the official forum about it, save one person 4 days ago mentioning the same thing. Might be worth posting on the Official forum:
