Paid Everything. Can't Use Tweezers? – Pet Foot Doctor Salon Spa Game Review

My kid really loves this game. Every time we try to use the tweezers an image of an iPad pops up and just goes up and down on the screen. We can do nothing. Paid $4.99 to unlock "everything" but then $2.99 to unlock all characters. Still can't complete single character because of this issue. And I blew $8.
