IFrame on Android

I'm trying to set up a form to work on mobile. I did the mobile responsiveness widget, embedded the iFrame code to my wordpress website, BUT in my form there is a signature box. This signature box on Android phones is bigger than the frame that is scrolling up; therefore, making the rest of the form useless. How do I change the size of the frame on Android to allow for scrolling? Or what is another option?

(The signature box in question is on page 2 of this form)

I see that you have embedded your form using iframe together with its script. Can you try removing the script part of the iframe embed code and see if that helps, please?

If this still not fix the issue, please feel free to contact us again with more details. Thank you.
