No beta reward for sniper skin challenge completion?

My gamer tag is ITS_THE_EXTREME I play on Xbox Series X.  I have checked my in game email and my skins in the game.  I am 100% certain that I completed the sniper skin challenge in the beta for the sniper ghillie skin with the skull face bandana.  I am just wondering what needs to happen to get my skin was one of the reason I bought the game thanks!  Please fix I really enjoy playing the game.
