Achievements, Stats and Unlocks

So right now i have been playing Halo on pc for 52 hours now and i wont unlock any achievements, banners and wont have any stats. i find this really frustrating because i’ve played through on legendary and put quite a lot of time into the multiplayer. please help :slight_smile:

I’m having the same issue. I’m going through on co-op and my friend is getting all of the achievements, but none of them are activating for me.
