A recent update of Facebook Messenger for IOS devices is consistently crashing with a session expired error. The app alerts:
Session Expired: Please re-login to renew your session.
Not sure if you all are experiencing it or not, but it’s crashing on iOS 6.1 over 2G/3G/WiFi.
I’m excited to check the new group feature added in messenger 4.0, but unfortunately the crash is keeping it away.
Are you able to run the latest version, please share a work around if it works on your iDevice.
