Is achievement unlocking still and issue?

I just started running through the campaigns with my son and he got tons of achievemetns in Halo CE and I got none. It doesn’t even show I completed the missions except the first one.

So we moved on to halo2 which crashed constantly in coop and was un playable so I started to play it solo and still no achievements.

I removed and reinstalled the game with no change. I’ts been about a month. I even replacyed through CE solo.

Any fixes? I found a bunch for the steam version but nothing for the windows Store.

i haven’t experienced any issues where achievements weren’t piping up, but i have experienced delays in the achievement popping. i finished a halo 2 legendary mission and earned an achievement for it, but it didn’t pop until several minutes after the mission was done
