Sorry if this has already been brought up, everything I found on this was old.

I've been trying to link my Facebook to my account, and when I go to Friend Feed --> Facebook Options --> Log In to link it, I get an error saying "App Not Setup: The developers of this app have not set up this app properly for Facebook Login." Is there any work around for this, or any suggestions as to how to fix it?

Thank you!

There are 2 bug reports on this (pages 2 & 3 in the bug forum), but neither has any replies. I suggest you make a bug report post and possibly ping the authors of those other two reports (Jack_OH_Spider and iara), to see if they've had any success for a workaround. As well, when those were posted there were several other big issues going on, so they may have been overlooked. Seeing a current thread that shows a few other people with the same problem might make a bigger impact.
