The Spotify App will not open on my IPhone.

[Mgambone5389]

I have an IPhone 5S with iOS 8.3 and I am unable to open the latest version of the Spotify app (3.0.0). Upon opening, the app will freeze and not respond to any touch commands. Occasionally it will proceed to the login screen if I tap the login button, but will again freeze when I try to type in my username or password. At worst the app will refuse to open at all when I touch its icon on my home screen. Reboots, redownloads, and resetting my phone by using the home button and power button have not resolved this issue.

Have you tried deleting the Spotify app and then reinstalling it?
