Why can't you leave the "Daily Challenge" EVERYDAY!! You should be able to work on it at the same time!! How ridiculous!! You've taken a fun, entertaining game and turned it into a miserable thing to play!! To many ADS, the ads don't run properly and you lose your bonuses! The time and trouble to access the bonuses isn't worth the effort. I quit playing everything in this game, except the daily Challenges. Now you only have them for 3 days!! You'll lose 1/2 your player this way!!
