Responsive Design Help!
I am new to Captivate - I'm using it for a project on a trial basis and was going to see if I could incorporate it into my teaching. As my students use multiple devices, I liked the responsive design feature of Captivate.

I have been working on this all day but I literally cannot make the title slide responsive. The text cuts off no matter how many buttons that I press. Here is how the first page looks like

This looks fine! And I assume that when I click on iPhone that it will as well...but

This is what it looks like. Part of the text gets cut off.
How do I fix this?
I know this is a basic problem, but it is what I am trying to do.
