I usually play daily and when the ads screen changes, it takes 'control' of the cursor too and if you are in the middle of selecting a piece or moving a piece, it makes the process extremely difficult. I choose not to pay to make the ads go away, but that doesn't mean that the game shouldn't play smoothly. I have carpal tunnel in my right wrist and this grab of memory in a short time period and nearly cestation of all movement causes me to have to make several efforts to move one piece. Deliberate or not, it needs to be addressed and corrected. I play as a dstraction and it's turning into a struggle.
