Full responsive – mobile view

Proudly we use your theme Business Pro (version 1.10.4) for our website.

The only thing we haven’t been able to realize uptil now is that the website is not fully responsive. When viewing the site on a iPhone or iPad the site is not displaying properly and sections are being cut off or placed far away on the right side of the website.

Could anyone give me advice how I can fix this?
I am looking forward to your respons.
Thank you in advance.

Kind regards
