issues with One Browser app on phone

[smsungal]

Hi everyone. I'm having problems with this browser on my phone. One Browser. When I log out from Facebook, I go back to log in the next time, but then I see it hasn't logged out. I also get this message to update my browser, and something about me using a browser that isn't supported by Facebook. I don't understand. This problem is recent. Haven't had this in the past couple of months...since I got the phone actually, which was back in March.

Anyone else experiencing this? Please let me know what I can do. I really love this browser. I tried Firefox, and also my phone's built-in browser...neither of which I like.

I have Samsung Galaxy s2 T Mobile.
