Black ops 4 achievements not unlocking

If a completed achievement hasn't appeared online after 72 hours, your console may not be connected to Xbox Live. If you completed an achievement or challenge while offline, you won't receive related notices or rewards until you connect to Xbox Live.
Once you connect to Xbox Live, try unlocking the achievement again.

 

Windows Phone achievements do not sync with Xbox Live

Global issue. Started a few days ago. Don't see any posts anywhere. This is different from the standard 'one or two achievements didn't sync' issue that Microsoft doesn't care about. It is currently impossible to get ANY achievements to sync with Xbox Live.
Live IS functional, however achievements do NOT update on any given profile.

Others sharing my issue:

Can't refresh (profile not updating)

Thanks for the prompt attention to this matter and I sincerely hope we won't be screwed out of the achievements that haven't yet synced, like when the last time this issue happened a couple years ago DDD

 

Achievements Defeat Death Itself, Death Do Us Part, Don't Fear the Reaper, and Forged Credentials
