Clearing Fluttr's data cache should resolve this issue.

The quickest and easiest way to do this on your Android device is to hold down your finger on the Fluttr app icon until a pop-up box appears. Tap 'App info' from within this box. And then, on the 'App info' screen, tap 'Clear data' at the bottom.

Alternatively, you can navigate to Settings, tap 'Manage apps', scroll down to find Fluttr, or type it into the search bar, tap on Fluttr, and tap 'Clear data.'

Clearing Fluttr's data won't affect your account in any way - it simply means that the app will be running nice and smoothly again.
