This seems to be a recurring theme. Try these steps on Android and let me know if they work. I'm trying to pinpoint the issue right now actually.
I'm not sure if it's the phone itself, the Android version, or the application version. It works fine on the LG G2 running Android 5.0.2. https://us.forum.tribalwars2.com/index.php?threads/android-troubleshooting.387/
