Solo legendary achievements not unlocking

Games Halo 5: Guardians
1

Hi everyone, as you can guess from the title, my achievements for solo legendary/heroic are not unlocking. On my service record in game it says I have completed the campaign legendary solo, but the 3 achievements related to this are not unlocking. The achievements themselves are at 93%. I have tried a hard reset and re-playing 2 levels and neither of those worked. I tried loggin in and out etc that did not work either. Yes I’ve read a few other forum posts about this but none of them solved my problem.

If anyone has a solution or advice for this it would be greatly appreciated.

Seems a lot more people than I thought are having this issue too, it is also happening with the achievement for getting all 13 skulls, that one is not unlocking either.

Yeah I have the same problem with both the Intel achievement and the Skull Achievement. I’ve collected all the intel and skulls but in the app it only say 69% for the Skull achievement.
Maybe the problem has been solved for you, but it won’t register for me.
