So every time I click on the app, it makes me download data to continue playing. I get that I would occasionally have to download data, but sometimes I will end up downloading a couple minutes after having last done it, which I'm pretty sure is not normal. At this point the game has taken up to much free space and I can't play the game on my phone anymore. Does anyone know how I can get the game to stop asking me to download more data?
