After upgrading my storm to OS 4.7.0.173 my facebook app has stopped working - notifications come in as emails not facebook events.
I've tried the usual things like battery pull, reinstall, full uninstall then reinstall. The full uninstall then reinstall worked... until I rebooted my storm, then the notifications came in as emails again.
One other thing I noticed: when doing the uninstall & reinstall the app got to the last part of the setup wizard after rebooting. At "connecting to facebook server" it stops, tries for a minute and then says cannot connect to server.
