Game crashes have made this unplayable – Hero Sky: Epic Clash Review

I spend gems to retrain armies after a battle and then the game crashes when I'm in a battle. It constantly happens and the developers don't support the game for that. iOS 10.x just doesn't work with the game. Played with friends for a while and now it is just unplayable, deleting and telling you not to bother.
