@dearapollo @BATJUICE123I also had the issue that i missed a Skin from the Campaign. Not everything, just one!
But with the last Winter Update it was available for me.
Just to know, have you checked the Weapon Skin in your Soldier Loadout(In-game) and the Vehicle Skin in your Vehicle Costumize screen (In-game)???
Because the Skins from the Campaign will not show up in your Inventory in the Main Menue! You just see them In-game.
