Total link mess on mobile – Dropdown Menu

Hello, I already tell that I’ve the dropdown menu problem.

I rolled back previews version, clear the cache, same problem.

Now I discover A HUGE PROBLEM :
With toggle “on” the dropdown menu, all the website on smartphone is totally crazy !!! All the links are totally random !

Check out your websites on mobile !

So for now, for me :
– Rollback previews version
– Un-toggle the dropdown

With that, links on mobile are OK. But menu is not working on mobile.

So I add a front message on my first page “Use a laptop or navigate with siteplan”… that doesn’t look serious on a business site… please correct that really soon !
