Halo MCC on Steam not unlocking campaign achievements

Games Halo: The Master Chief Collection

So I finished the campaign a while back on MCC but I was on Linux (hence did it with EAC disabled). I figured that’s why I never got the achievements before.

Now, I’m playing it on Windows for achievement hunting. That’s when I’m starting to get the achievements, but after Reach’s Nightfall mission, I stopped getting them.

Any idea what’s up? I see multiple posts in the forum, and I’m not sure if that’s PC or Xbox.

Achievements are broken for both systems. Many of them will not unlock,

Either they unlock eventually or the recent update broke the achievements again. Submit a support ticket for this and keep playing
