Achievements not working

Quite a few of my achievements aren’t activating. Is this a common issue?

Ive definitely had achievment “lag” and some that ive done twice but that is across multiple games so in guessing its just an xbox problem (my xbox is from three months after launch so it is kinda old)

Hey folks, there’s a pinned thread in the support forums that’s being used to track achievement issues. Feel free to add your reports there
