I have a clickable Instagram icon in my navbar, which is shown perfectly on all devices except for the mobile landscape mode. In the Webflow preview mode it is shown, but on the actual mobile device (Huawei p20 lite) it is not there/I cannot scroll down to see it.
This tutorial might help you resolve the issue where the dropdown menu won’t scroll when open and instead the page scrolls leading to items in the menu that cannot be reached.
