A few weeks back Facebook once again broke the OpenFlights app, this time in style: by deprecating a critical API call, status updates started to aborted halfway through, causing some people to get an incessant stream of spam since the status went through, but the fact that it went through wasn’t recorded. Gar! My patience with Facebook long since exhausted, I simply disabled the updater for time being, but fortunately Niko was kind enough to send us a patch that seems to fix the problem and adds in country names to your updates as a bonus.
So, long story short, if you disabled your app because of this problem, you can turn it on again. But it’s only a matter of time until Facebook breaks it again.
