Since the Immortals Fenyx Rising free to play weekend in late November 2021, none of the Ubisoft Connect challenges I've completed in AC Valhalla have registered on my account.
This includes time-limited challenges (various solo and community-related ones through December and January) as well as the core ones, such as completing the Paris DLC, or getting the Swordfish by completing all the fishing requests.
I've seen this was a problem back in September 2021, but nothing has been reported recently. It's all a bit strange, you can see in-game numerous ones have been finished, but Ubisoft Connect is refused to log any.
Ideas anyone?
