1. Xbox One
2. A lot Extra achievement not unlocking
3. In game missions show I have every optional and bonus objective completed. I have played through each mission more than twice on different difficulties to get the achievement to progress and it won't increase after 85%. In my service record on waypoint, it shows I have 64/65 sub-objectives, but from what I have seen, 64 is the number needed for the achievement to unlock.
Please feel free to message me if there is anything I can do on my end to get this resolved.
