Game not starting under iOS 8.3

[Cidro]

Hey everyone,

I just updated my iPad Air 64GB LTE to the newest iOS Version 8.3.

Since then I am not able to start the game properly. It freezes on the Nexon Splash Screen.

It stays there for ages, nothing happens (neither does the game crash, nor load).
I already tried closing the application and opening it again.
I already tried deleting the application and reinstalling it again.

Nothing makes the app start.

Any one who experienced the same issue or knows a fix?

Cheers
Cidro
