This is happening to me with Skype preview installed. All facebook contacts aren't showing online and when I look at my "background tasks" it shows Facebook is being disabled. and I cant seem to get it working againYou guys still having this issue? I cannot seem to recreate it on either a Windows Phone 7.x handset or 8. So all contacts disappear after a few seconds, or is it just Facebook that's affected?
We don't believe this is an issue with Skype.
