While using this theme in the mobile version I have a problem.
When the hamburger menu is open and I am scrolling down, the scrolling does not stop with the footer.
The same thing happens even when I am scrolling right until the top bar appears, even though I can read it only halfway as half of this bar remains out of my screen. It seems like it is showing me a larger version of the website instead of what it should actually be for a mobile version.
All this, however, does not happen if I open the the top bar first, and then the hamburger menu.
The features that you are facing problems with is actually the feature that is offered by the theme itself.
The changes that you want to make to the theme needs a higher level of code customization and hence, you need to hire a professional developer.
