I was playing, I had run out of moves and I decided to watch 3 advertising videos for more moves, everything was going well until the moment they had to give me the reward, the screen froze and it wouldn't let me select anything, the only solution was to exit the game, I lost lives, rewards and a match I was about to win, this is just a complaint, I don't want anything in return. I have proof of what happened, I hope they fix that
