I tried to load my site in Chrome for iOS on my iPhone 6. Check out the video of how it loads strangely and adds white space to the right by default. Of course users can zoom to fit the screen, but that’s not the best case. Do you know why it does like that?
BTW I really like the theme and consider buying the pro version. This is just a test domain to find out if it fulfill our requirements.
Not sure I can say what throws it off. Could you first try switching to a decent sized image? That would make things load faster and might help.
Might also be related to some plugin you have on your site, considering that this does not happen on any of our demo layouts.
