I have set the position of primary navigation below header but outside the customizer or in another browser it is above header.
I was trying out something with the customizer, e.g. mobile settings, sticky menu and so on.
Can I clear some caches? But I have not set the cache on.
I did try something: Exporting and resetting all setting – nothing changed.
Then I have dectivatet GP-Pro. Now the menu is on the right position, but I need the plugin …
After deactivating, the menu is still on the right position.
I´m hoping, that this helps in future too, if I have this problem, after the go-live …
