The in-game Ubisoft Connect interface does not appear to exist for me anymore. Trying to bring it up from the main menu or the game menu does nothing. Tasks required for the weekly challenges do not register on the Connect client game page challenges list.
Possibly related to this: I get two "The procedure entry point CreateDXGIFactory2 could not be located..." errors when starting the game. This problem was raised in the forums several weeks ago by another user who got no official answer or assistance. There was a suggestion to verify game files. This does nothing.
