Assassin's Creed Unity won't download

Yes it's been stuck at 72% forever

 

Assassin's Creed Syndicate achievement's not unlocking

Flawless Conqueror

Thieftaker

Children's Aid Society

Furious

Queensbury Rules

Whirlwind of Death

All of these should have unlocked but didn't. Most of them are stuck at a certain percentage completion and won't advance. The furious achievement is stuck at 92% and won't progress for instance. I've tried clearing the xbox one cache and deleting and re-downloading
my xbl profile. Neither worked. Several of them have been stuck for more than the recommended 72 hour waiting period.
