Waypoint scores and times aren't updating

Played Covenant in Halo 3 twice yesterday, and the time and score didn’t update either time. I played on legendary and beat the par score and got a time of about 30 minutes, twice. Didn’t update in waypoint either time. Then played other levels in H3 and they updated on waypoint fine.

Why won’t this one level update my scores and times in waypoint?

On Halo 2 I have completed Regret twice and Gravemind once, both levels were done on legendary, and none of that progress got saved on Halo: MCC or Waypoint. Best time on Regret was 13:58 and Gravemind was 30:44. I had to complete Sacred Icon twice, The Great Journey 4 times, and Quarentine Zone I lost count how many times it took before it registered my time. It is incredibly disheartening to speed run a level on legendary and it not count.

Any explanation for why it only registers some of the time???

So my stats in waypoint haven’t updated, BUT, the achievements just popped for Devastating (legendary in 3 hrs) and Vanguard (score on covenant). So my score and times are saved somewhere and triggered the achievements.

So I guess i’m content, because the achievements are all I really care about, but still strange that one map’s stats won’t update on waypoint.

well im not content…this is absolute BS that 4 month plus old topics/problems arent addressed nor FIXED. Just finished the best time I could muster up on a legendary campaign level only to find the last hours I spent saving/reloading to keep good times was for NOTHING…because the F"N TIME DONT COUNT OR REGISTER HALF THE TIME. 6 months after launch and issues like this not addressed/fixed means i’ve lost respect for 343 has a competent developer and now have moved them over to the same list as BUNGIE marked as not buying ONE single game from them the first year of launch. Have to give these incompetent developers a year to finish these half baked games and no need to rush into another broken game like this one from 343 toilet industries.
