Facebook sharing disappears when app is installed.

I have begun noticing recently that when I attempt to share something to Facebook from my phone using the share button, it is not working correctly. In one of my apps, it shares it blank, instead of containing the text I want to share. In others, the option to share to Facebook does not appear at all. Facebook reappears in my list of options for sharing only after I have deleted the Facebook app itself. When I delete the app, the text appears correctly in the sharing screen in the one app and the option appears again in all the others. This problem occurs on both my iPad and my iPhone.

Has anyone else encountered this problem and found a solution to it besides deleting the app? I encountered a similar problem with Twitter a while ago that has since been resolved.

Thanks,
