Official Facebook app doesn't work after upgrading to developer preview

[rpkay]

After upgraded to windowsphone 8.1 preview I can't access facebook app.
When I pin it to start screen it shows like it's been installed to SD card and removed the SD card.
In the store just like other installed apps. options like view or share can't be seen.

It's a fresh install, previously I was using facebook beta app, since it doesn't gives notifications in action centre, I installed this now it's not working
