Halo Wars DE Achievements not popping

So I installed it today for Xbox One, and the first few campaign achievements popped no problems… But from Arcadia Outskirts onwards, I’ve not had a single achievement pop, campaign or otherwise.

I’ve disconnected and reconnected to XBL, removed and reinstated my XBL profile, fully shutdown and restarted the X1, and still nothing. The only option left is to reinstall the game, but I doubt that would effect anything.

Help pls?

Bumping this because obviously nobody’s replied… It’s been a few days now, and still these achievements aren’t popping like they should be. Especially the multiplayer achievements. My service record already states I’ve met the requirements, yet the achievements haven’t popped, and some only have a random percentage to completion number.
