I have a website with the header to the right (https://cigarsbyjorge.com/), on desktop if works fine, but on mobile there is a white space to the right, where the menu should be when open.
The solution I found was adding this custom css globally:
@media only screen and (max-width: 768px) { .x-bar-space-left {display: none;} }
Please, take a look, the issue is still there on the stable version
