Spartan Ops Invasion achievement

Games Halo: The Master Chief Collection
1

I just finished playing through chapter 7 of spartan ops on solo legendary. I have not logged out of the game so I can still see all the completion emblems. However, the achievement is stuck at 80 percent. I could play through it all again but that wouldn’t stop it from simply not unlocking again as well. Thoughts, ideas?

Edit: the achievement popped after ten to twenty minutes of sitting in the menus.

As I posted this it popped up lol. Guess it just took waiting ten to twenty minutes.

Glad it unlocked. MCC needs time to sync everything up at times so waiting solves some achievement problems.
