App is useless. Displays nothing. Can only view usage for a couple of months ago, and even then it's just a single number - no breakdown. Can't easily view bills. Couldn't even find my account number in the app to fill out this feedback form... The values on the usage screen don't match the values on the billing screen at all. Can someone please tell me what the point in this app is? I can not find any reason for it to exist.
