I too dislike this trap. Have hit it 3 times now. The "button" is too big. It appears to be the small purple button but really its the whole rectangle which makes it easier to tap. I collect my crops and boom window pops up and it's too late...
Change it back. At least before the button was smaller and less in the way. Traps still happened but it was less often.
I will not be buying gems anymore if it is so easy to throw my money away.
