For a couple days now, whenever I try to download an app from the App Store on my iPhone 5s with iOS 8.3, it brings up the 'use existing Apple ID' or 'create new one' window.
When I select the existing one and fill in my account information it closes the pop up window and starts to download the app (indicated by the circle starting to turn) but after one second it goes right back to the 'get' button.
When I try to download it again it all goes to square one. İt has been driving me nuts! İts like a vicious circle!
