Instragram in not allowing me to share to facebook

I have had an iPhone for years and always share from instagram to facebook automatically. Recently I tried to do something on my instagram app with making it a business account, but didn't follow through and now no matter what I try it won't allow me to share at all to facebook. I have logged out, uninstalled both apps and logged back in. When I try to go in settings on instagram and click on share to facebook it brings up message to connect to facebook, I click on it and it just keeps disappearing and the button slides back showing not connected. Please help!!
