I recently completed the first 3 yellow battles, then moved to the first white. I won the battle and was awarded the gem for having 4 battles completed. However, the battle is still showing white for me and it allows me to play it again.
I encountered the same issue. I got the reward for completing Biweekly and it was counted in the achievements, but the battle is still white. Could be that I did only the last battle after the minor update.
I had the exact same issue but for all of the battles along the bottom. I did the first and second 2-3 times before deciding to just do the others once each and see if I got the rewards… which I did. All of them are still possible to replay.
Thank you for the report.
This is only a visual glitch. It won’t affect any rewards or achievement.
This issue has been fixed. We are sorry for the inconvenience.
