Finish your app, THEN upload it.
Like so many others, the steps that I have to go through to log in are first: open the app and look at a green logo screen for about 60 seconds before it crashes once. Then second: open the app a second time an log in again, even though I have used the app within the last 10 minutes and am definitely already logged in. Really, this app is constantly updated with new features. Why cant you fix the absolute MOST BASIC FEATURE: LOGGING IN? Please finish developing your app, then upload it to the app store.
