I have attempted to use the hand swap booster a number of times. I tap the booster, confirm it is flashing but when I swap two candies, it usesa move rather thanthe booster. It is often my last or second last move to win a level and I lose the level. I've seen other posts with this problem but no solution. It is impossible to send a screen shot because how do you screen shot something in the past? Please provide solution. Thank you.
