This is an unusual problem...
Well I would suggest is to completely remove the app, and then re-download it, and see if that works. Make sure your not pressing the Log out button because it's easy to press it on the main screen...
And if the problem still persists, contact Apple, or restore in the most extreme cases if your apps are getting as well affected.
