Have GP Pro installed. Have “Use Navigator as Header” checked. When clicking on the Menu button on a mobile device it works sometimes but does not detect the click most of the time. I read through the forums and tried several things with clearing cache, reinstalling GP, installing CSS. Nothing worked. Then I unchecked the “Use Navigator as Header” and it works. So, I believe there is a bug in the “Use Navigator as Header” code. I don’t need support, but just wanted to report issue. I installed the hooks and CSS to make the header sticky and it all works now.
I appreciate the theme and the support forums. I’m usually able to find a post with a fix whenever, I have an issue.
