Want to know why? Because it doesn't let you reset data. I am having a major issue with one of the games on my phone not recognising any achievements that I get on the game and saying achievements that I haven't gotten and I wanted to reset the achievements for the game and start over but there is no way to. It's ridiculous. You delete the app and supposedly delete the data and then when you try downloading the same app again the same annoying bug occurs. Seriously you think apple would understand the simple prospect of RESETTING data
