I recently signed up for Pro for access to the step-by-step solutions, but they don't work for me. I see the beginning of the solution, but then it's cut off. There are no buttons to step through the solution or see the entire solution at once. I can only close what little I can see. There's a print icon, and I was hoping to at least be able to print to pdf or something and get the full solution, but that button seems to do nothing.
