Submit button on iphone/ipad not visible

The submit button is not visible on iphone or ipad. The submit button on desktop browser is visible and browser can be resized to iphone form factor and it is still visible. However, when viewing on iphone or ipad you can click the submit button but it is not visible. I have added css to the theme customizer targeting the submit button for that form and cannot get it to work. Roof Inspection | Qtmbuilders.

Hi,

I was unable to reproduce the issue, and the submit button was working fine on the Safari browser. Is there anything I’m missing there?
