Instagram won't connect to Facebook
I can't seem to connect my Instagram to my Facebook. When I go to share my Instagram on Twitter, Tumblr, Flickr, etc. it works fine and connects. However, when I click on Facebook I get the error message: "Facebook Login Failed - Make sure you've allowed Instagram to use Facebook in iOS Settings > Privacy > Facebook." I went there and Instagram wasn't even listed. I uninstalled both apps, reset my iPad, removed Instagram from my Facebook, reinstalled both apps, tried to connect with Facebook again yet it keeps showing the same error message. Any help would be much appreciated. Thank you.
