Inconsistency when signed in with tow different credentials
<p>I signed in into the app with some credentials and that user has some data that is downloaded through web service. The problem is that when I sign in using some other credentials after signing out(not exiting the application), sometimes I get the data of previous user. Can anyone tell what could be the problem. What can I do when I log out to delete the data related to previous  user.</p>
