I used to love this game, now every time I try to do the daily challenges it freezes and the game will close. When I open it again it makes me watch an ad to try again, then closes once the ad has finished and will loop like that until I give up. The puzzle party challenges are just being recycled now too without taking into account the different abilities of some cards - meaning that some challenges are unable to be completed and therefore you're not able to complete your challenge week.
