I'm using Version 2.1.0.28 of Twitter on my 9930 (version 7.0 bundle 1739) and every thing was working fine until a few days ago I stopped receiving notifications of tweets and mentions and when I open the app in my @ mentions section it says I have "no tweets available" when I know I do!
I have tried uninstalling, rebooting, battery pull and nothing helps...anyone else having this problem??
