So step by step my actions are as follows:
1) Settings
2) Accounts
3) Sign in on Facebook
4) Enter email and password
5) Give Kobo access to my public profile
6) allow Kobo to post on my behalf
7) Here I am presented with a screen that says Success in the top left and on the next line there's an explanation to treat the URL as a password and not show it to anyone. I must note that AT NO POINT throughout the process has there ever been a URL visible. There's a link to Facebook's help center that I can't click (it doesn't act as a link).
At this point nothing happens. There's nothing for me to click and I can only close the dialog/window (whatever you want to call it) which sends me to the home screen, or I can back out of that screen into the Accounts section of the settings menu where my Facebook account is still not linked.
If I don't manually remove the login from Facebook I am immediately presented with the useless Success screen after I enter my login details with no action forward.
