Constant crashes and freezes – Assassin’s Creed® Unity Companion Review

I can't even say if this is a good app or not due to the fact that every single time I try to sign into my U Play account, it freezes and crashes. Extremely disappointing, especially since I need it to achieve 100% completion on my game. Please fix this.
