Hey I need help... My castle clash app would download but when I try to open the app, most of the time the game crashes in the loading screen

Try and delete the app +cookies if possible (u wont loose heroes or anything else), and reinstall it.
But could there be problems getting a full or good signal on ur network? this can also make the game crash when tryin to load.

Hope u fix it

Or maybe there is someone who has better tips?
