There is a solution for Android users but it is too complex to describe here. If you are technically minded it can be researched online. I have the same issue on one of my games but TBH it is not worth the hassle for me. It may however be worth it for others. I prefer to keep the game with the boosters as it stands as it is the game which I completed most levels on, which I like to go back to and I'm not interested in passing any new ones.
