Facebook appears to have changed the SSO page so that users can't log out / switch accounts directly. What I mean is this:
a) you have any iOS App installed that uses the Facebook SDK, for example Voxer (not my app), and you do do not have the Facebook App installed
b) you log in normally via Safari
c) you log out again and try to switch the user, but the screen displayed on Safari only allows you to sign in the same user again (OK Button).
It is possible to navigate to facebook.com and log out there, but that is not intuitive at all for most users. Telling people to install the Facebook App is not very user-friendly either.
I have found nothing about this either on developers.facebook.com or here, am I missing something or should I submit a bug report?
Thanks,
Sebastian
