Same happens to me on PC Win10. I can't get the S-5 officer pistol. For other rewards that weren't activating, I stopped the game, went into Origin, selected Repair in the options for Battlefront2, then restarted the game. The only one not triggering is the S-5 pistol one
So I just completed the Order Shall Prevail challenge and of course I can't collect the reward because EA is too STUPID to test their half-* code.
I was able to fix this problem. How? I took out my wallet and threw money at the screen. Let DICE do its thing, EA. You'd make more money that way, and we all know you LOVE money.
