‌This is the second time, within a week, that I have completed a challenge but cannot receive the reward.  The previous issue, which still remains, is the IQA-11 Sharpshooter challenge being complete, but I am not able to receive the reward.  I would like to add that I have noticed these milestone issues may have to do with not being able to quit after each round.  For example, I have noticed, over the past few days, that if you complete a match, go to the scoreboard screen, and try to quit, the game will keep going back to the scoreboard, and you have to try quitting many times.
