Dont know if anyone else has been experiencing this problem. My latest version of the blackberry Facebook app (1.9.0.20) leaves messages in my inbox folder...and when I try to delete them individually or using "delete prior", they won't go away...but it still shows that they are there...even though you can't access them. I also tried deleting through ''notifications'' in the actual facebook app.
I've tried uninstalling the app and reinstalling it. Doesn't help.
Also when I attempt to delete the message out of my message lists, it will sync with my Facebook account deleting any messages there.
This is totally driving me nuts! Didn't know if anyone else was having similar issues or knew a fix!
