Unfair changes to Tractor Dash

Originally, all you had to do was to earn more stars than your randomly chosen opponent to win the prize. If the app wasn't running when the timer expired, you got the prize when you opened it the next time. Now, you also have to have the app running when the timer expires. Otherwise you get nothing. It is very unfair, as it's not always possible to have the app running when the timer expires. Let alone having enough charge for the device to be switched on. So can this be changed back to the way it was? It's not so much for me, but I'm sure there are plenty of other players who are missing out on a booster that they may have to rely on to finish a level.
