I was installing apps and icons and I notices that there were about 4 games installed, so I went to software centre to remove them then I wanted to add my Facebook account in Online Accounts but Alas! It was disappeared. But it was there when I searched for Online Accounts in Unity Dash. Please help me. I think I might have uninstalled wrong packages. Can anyone tell me the packages that are associalted with them. I am attaching a screenshot of my settings and the Online Accounts appearance in Unity Dash.
