Anyone else here completed more than 5 fiesta matches and have had no progress accumulating with the challenges? I thought they had a update for this? Wasting my time
Its wins not completions
Its a typo
Biggest waste of my time ever.
Why? Its only 5wins and you still have 2 full days and abit…
If I could post the image of my game screen being frozen I could show you but halo waypoint won’t let me, therefore even wasting my time even more
While I share your frustration, if you had devoted a few moments to scrolling through the topics, you would see that a lot of people have already created a discussion thread on the exact same thing. That could have actually saved you some time. 
Reboot the game? Im confused what that has to do with the challenge
