On iOS mobile, I played “Watery Grasp”, and then my opponent immediately played “Watery Grasp”, and then I immediately played “It’ll Quench Ya” to counter my opponent’s spell. The mobile app would not let me click on the opponent’s spell to target it. The cards seemed to be stacked on top of each other, and I could not trigger a click event. I could only target my own “It’ll Quench Ya”
