I also set listener for event …
Could you help me please ?

It works fine on iOS iphone 6 simulator but not on my iPad mini with iOS 8.4.1, strange… Should i add flag or something else to avoid error after login ?

Let me ask @nite to help with this.

Looking into this crash

Works for me:

  1. iPhone 4s (iOS 8.4.1),
  2. iPhone 6 Simulator

strange…
