I'm having the same issue (PS4). Played a few hours last night, whenever I was told during play that I had progressed enough to claim a reward, upon exiting the multiplayer match and returning to the main screen, progress was not gained and the reward could not be claimed.
Super annoying.
Same issue here, 25/26 MP milestones, allthough every one is completed. Nothing I do fixes it, I've tried doing the disrupted enemies milestone again, and the defender / aggressor milestones. Nothing works. And nobody is answering me if it's gonna be fixed.
