A couple months ago I was playing one of the special challenges, once it was over I had lost all the boosters I had up to that point. I had been playing on the same platform, my galaxy phone, and there hadn't been any connection issues. Recently I upgraded my phone, installed the app and the boosters I had acquired since the last time have all gone away. Why can't these be tracked and kept for the player to use. Should be tied to the email or other unique identifier.
