I’m having the same issue as well. The issue is once the screen size is below 1000px wide the menu display block is not triggering anymore. The code in the style.css of the theme requires updating ASAP.
This line of code is currently set to: display: none;
when it should be set to display: Block i think.
@media screen and (max-width: 1000px)
Please look into this ASAP as all mobile dropdown menu doesn’t work if you are testing while logged out of wordpress.
