I seem to be unable to accept and invite to a notebook that my teacher has set up for the class. Whenever I get to the page that presents to me with the "Join Notebook" button, it is unresponsive. Though the animation of it being pressed is still activating no cpu process begins and as a result nothing happens. I'm not sure what I'm doing wrong, or maybe this is a bigger problem than that. If I could receive some help that would be great. ~Attached is a jpg of the screenshot of the page.
