New problem after adding clearcache=yes

[tssa88]

I had that problem which the app would not logout. I followed the instructions to add " clearcache=yes" to the end of ther URL, described here (#10). It worked (IN PART). It's already logging out when I click the button to do so, but the problem is that it's also logging out when it's not supposed to. It should keep me logged in if I kill the app and reopen it but the app is asking for my FB credentials again. (I'm not explicitly clicking the logout button)
How can this be fixed?? Thanks.
