So I found issue occurs when the viewport height is not enough and user need to scroll to see all the nav links, but on mobile portrait where viewport height is enough this issue doesn’t occur!
Sorry for not mentioning earlier but this happens on published site, webflow’s own domain. Please see it on your mobile browser on landscape mode or by the help of chrome developer tools where you can manage screen size:
Yes it works fine until you have screen real estate enough but when these nav links go outside of the viewport in landscape mode it starts bothering. I checked it iPhone SE on chrome and then iPhone 12 pro and that’s what I see, if you can see it on any mobile device landscape view you may find the issue but it will only happen if the viewport is not enough and you need to scroll. Here’s the image of my test with chrome developer tools which you can access by CMD + Option + I on mac.
