this app has been really helpful to me as I use it to communicate with my friends. But now, I don't know what is wrong with the app, I keep on tapping 'cancel' to stop the update cause it's taking too long than usual, but my phone only ends up crashing and always gets stuck. I press the 'back' button and now it doesn't work. I don't know if it's the facebook app or Playstore app that is causing this or if it is my phone, but it only happens to Facebook. All other apps are fine. PLEASE FIX THIS.
