I am on day 250 for consecutive daily challenges. Today's is Run 750M in One Run, Without Coins. I've completed it 4 or 5 times, but it never will give me the chest, the reward, or credit for completing the challenge. Of these, I want the credit most in order to keep my streak alive. I've even tried to run it on a different map. Even tried running 1000M with no coins and then dying shortly after with no coins. Any ideas?
