Hello all.


I apologise in advance if this has been asked before, I did a quick search but I couldn't find what I was looking for.


I have been having an issue in the past 3-ish months with photos that I share to Instagram not automatically being shared to Facebook, even though the two are linked.  


I have googled the issue, and followed all the steps to fix it - but to no avail - it still won't share.  


Upon further investigation, I can tell that the issue isn't with Instagram, but with Facebook permissions.


Under Facebook Settings > Apps and websites > Logged in with Facebook


there is a list of apps that are logged in - and Instagram is missing - BUT - and this is the issue - I cannot seem to add Instagram onto here, and I can tell that this is the reason why it isn't sharing!


Can anyone help and tell me how to get Instagram on here?  The app just won't show up.  WHY???  Anyone else have this problem??
