Everything works on desktop and landscape mode on mobile but in portrait mode on mobile, the menu at the top starts flickering (hiding and reappearing). This is only a problem with the “floating” mobile menu which appears once device screen is narrow enough. Flickering only occurs once the page has been scrolled down so much that the menu sticks to the top of the screen.
This same happens on all my Swift Premium sites and i have tried disabling plugins. How can i fix this? I’d be happy if the menu would just stick to the top of the page and disappear from view when page is scrolled down.
