Hello,
Recently I had to change devices and when I logged in the game I was surprised to see that all my boosters were gone (more than 100) and I don't get any adverts to help me progress, get new boosters or pass a difficult level. Apart from annoying and frustrating, it's also extremely unfair to players, like me, who have spent a good amount of time and money to get yo the level they are and now are being punished for changing devices. This has become a nuisance to the point of considering leaving the game. Really bad customer care yo say the least
