Hi there,
I have come across some issues with the desktop and mobile versions of making the topbar sticky along with the navbar. I have managed to make the topbar/navbar sticky - but when you load the page the navbar is slightly higher up ‘underneath’ the navbar, maybe by aboout 20 pixels. When you scroll down, it fixes itself and repositions. On mobile, the navbar being ‘underneath’ the topbar is even more prevalent - it seems to be under it by at least 50 pixels.

Please let me know what I should do. Many thanks.
