I think Gameloft has stopped supporting the game on Windows phones. So there is hardly any chance that WPs will get an update anytime soon. For now they are just focusing on iOS and Android.

Sadly if you change your device you'll have to start playing the game from the beginning as there is no way to transfer progress from one OS to another different OS.
