Multytap problem again

I have again multytap problem in game when I want to activate spells.

I have this problem about two weeks but I didn’t paid so much atention to that because I succeeded to acitivate spell after two or three hits.

But last few days it’s geting worse, and two or three hits on spell is not enough anymore , and the biggest problem is because this happening in crucial moments in fight.

My first taught was that I have problem with my phone, but then my teammates confirm that they have the same problem on Android and iOS phones.

My Phone : Honor 8

Android 7.0

Game version : 4.4.3.
