Reinstall or not reinstall? That is the question

[Ivandadajet]

My app seems to keep on freezing from time to time, sometimes it won't recognize,e and starts telling me that a game center account is require and I have zero points etc etc... I have reinstalled the game many times and that fixes it most of the time but I am tired of doing it, I should not have to! is there any way to avoid having this issue ? Also, I think the reinstalling may be affecting my ranking, I am number one in a gifted league but the next person is 1000 or more points below me, it does not make any sense, will I always be in gifted regardless of how many points I earn?

Thanks

Ivan
