Tons of spam windows
After several months, not playing the game, I couldn’t remember why I weren’t playing it. So I decided to update into the game immediately getting bombarded by tons of windows wanting me to purchase several kinds of endgame currencies or spamming me for participation in a huge variety of missions or events. At the same time the game required me to reject all of these requests on different part of the screen not to risk ending up in a purchasing situation. I didn’t even get to a point where I was able to actually play the game before I became so frustrated about all the spam windows before I almost threw my iPad across the room in frustration. My suggestion is to stay away from the game.
