I am sorry if this is another thread and please include a link to the thread.
Both my wife and I are having problems with the new updated app. Every time we try to use the apps, the login screen pops up. After entering my information correctly, it remains up. If I clear up so memory and close all my open programs, including when there is only one open, I can make it work without the login screen popping up. I am running android 4.4.2 on a Galaxy Tab 4.
