This is perhaps a weird question, but I haven't found the answer anywhere. With Ubisoft's cross save functionality coming, does this mean that when you play this or Watchdogs Legion on PC, and then a year later switch over to PS5, while using your cross save to continue playing where you left off, do your trophies retroactively unlock?
