Same problem with Bryan Duro i'm also experiencing everytime I try to attack players of higher rank than me, I will recieve a notice that says "Server Failed to Process Request", then will route me back to the to the title screen. Also i have a 100mbs internet and the app is also up-to-date. Hope it will be fixed by devs i always writing this review but for some reason its always deleted. The gameplay is fun and the graphics is good.
