If you’re a heavy Facebook user on your iPhone you probably noticed every now and then that comments are displayed wrong. For instance, when you just upload a new picture, sometimes Facebook displays comments on it that were received for other ones, mixing content up.
A new update is available in the Apple iTunes App Store that addresses the comment bug. Facebook has now reached version 4.0.3 and just about the only thing we noticed (and that’s listed in the changelog) is the fact that it “fixes an issue that caused incorrect comments to be displayed for certain photos”. Follow the source link below or consult your iTunes/App Store apps to update your client.
