Achievement unlocked yet also not?

So no clue how else to exain it other than i killed a thrown grunt for the acbievement. On my xbox it doesn’t say ive earned it. But my phone through the xbox app does say i have it. Ive never had my app say inhave an achievement but my xbox not, so im not sure how to resync them so my xbox reflects that. Anyone have any idea?

Rarely, achievements do fall out of sync. Restart your Xbox may work, if not you will need to restore your account on the Xbox.

I would verify that you have the achievement through Xbox dot com or a third party such as TrueAchievement.

If it’s unlocked on Xbox it will show at some point. I had some just not unlock so I had to repeat the action on a fresh save like ghost splatter.

Weirdly enough I unlocked the kill all high value targets trophy before I got the kill one ha. It only unlocked when I killed one on my next run.

Thanks guys. Yeah on xbox website
the xbox app, and true achievements all say i have it. So ill just be patient. Its more so like “im almost done with second playthrough and ive only seen a grunt get chucked 1x” annoyin vs laso didnt unlock annoying xD
