If you're having trouble seeing a persistent login window, try quitting the app and starting over. To do this:

1. Go to the the Home screen of your iPhone or iPad.
2. Double-click the Home button to display recently used apps.
3. Tap and hold the app until a red minus appears.
4. Tap the red minus to quit the app.

When you open Readability again, your login should work right away. If you're still having trouble, we recommend restarting your iOS device or removing the app and re-installing from the App Store. We're working on a permanent fix for this issue in our next app update.
