I use a custom fullscreen overlay menu for desktop. Links to other sites (e.g. Instagram) don't work at all and links to sub-sites direct to the correct url but load and show the current page, where I've already been. If I press reload then, the correct site is shown.

Maybe, someone can help me out here. I've been searching for answers for hours now, but unfortunately can't find any :/
All the best!
