Is anyone else having trouble unlocking achievements? I’ve done a hard fight heroic campaign a couple times and it still hasn’t unlocked? Is there a problem with achievements right now?

Yes, this is a VERY big problem. As you can see on my service record I have completed the original campaign on Legendary and Heroic but still haven’t received credit, which sucks because I am a completionist. In conclusion it’s very frustrating and 343 needs to work on this

Hey OP, there’s a pinned thread in support you can use for logging / tracking achievement issues
