I am having LOTS of FB and Instagram issues with IOS 6 and my iPad. I did the Restore with Back Up and THAT didn't work. Then I did the RESTORE and it seemed to fix OTHER issues but not the FB one. I can totally READ my Facebook feed...but I cannot post a status, share or share/post photos. The same thing happens with Instagram as well...Apple says that it's the Apps problem...not IOS 6??? Has anyone gotten answers from FB at all??
Open ur account from a computer send FB. Ur problem while ur logged in then w8 a while about 5 min and try again I had to problems I had the login error and I couldn't refresh my news feed as soon as I contacted them directly they solved my problem in no time.try it before u judge :) I WISH THAT WILL SOLVE UR PROBLEM
