Previously I had notified this error after a recent update, although before the system was update I had already had problems to carey out attacks in the coliseum and the war. The error is that when I start the attack in one of these two game modes, it start to charges and inmediately leaves the game, losing the changes competing in a battle of war and advincing in the coliseum, which of course i have been degraded this, losing the rewards. Please @Polaris , I need an answer to this because i about to be degraded for the third time…
Youll keep experiencing it til next month/update… its started with 1.7 update…
