Hack glory of generals 3

[alessiop]

Hello
my intention was to go and change the value of the coins (the value at the top left in the first photo) within the game of the game "glory of generals 3", a famous game about the second world war just released for both android and for IOS
I tried several times, but always without success (I only managed to change some values, such as the Hp of the various units, but when I try to increase the coins nothing happens and sometimes the game crashes), can you help me?
Thanks
