Inspite of me winning the 3rd challenge your app gives me mission failed, there is a green tickmark I get and then it shows mission failed. You guys are cheaters. I retried the challenge 3 times. Everytime the same nonsense happened. I hate this game where you people cheat. Also the gift boxes that we earn in the game are a reward of clearing 5 or 6 levels in a row, still to open the gift box which is my reward, I have to wait a long time watching an ad which is compulsory to get the reward.
