Foundation Topbar only works after refreshing the page

Very annoying! I’ve tried a dozen settings, no better result. Loading the webpage on an iPhone or iPad, at first the menu is not clickable. Only after refreshing the page, the Topbar works. How is this possible and how can I fix it?

Can’t help with a fix if we have nothing to look at. Got a URL??

Seems to work for me just fine

The problem exists on iPhone and iPad

I’m not seeing any issues either - perhaps its your browser cache

Oh crap, wrong video, sorry about that…

Here is my iPhone video, fixed link above
