Hi Henry,

I hope you are well today and thank you for your questions.

The first in the parent menu elements that contain submenus, does not allow me to access when clicking or pressing the parent element.

I could confirm the issue on my test site therefore notified the theme developer about this so that it will be fixed.

The issue will be fixed ASAP.

And the other problem is also presented in the menu, I have a certain amount of menus, but clicking does not allow me to go down to see all the menus, simply down the screen but not the menu.

You can resolve this issue by adding the following CSS code in the Custom CSS code option of your theme on the below path.

Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code

.sh-sticky-mobile-header {
    position: absolute!important;
}

Best regards,
