Hiding items above header

Hello all,

I am facing an issue with my header on my pages. It looks perfect on both desktop and mobile browsers, however, after adding our app to the app store and accessing it through the home screen (progressive web app), the items seem to be scrolling past the header.

Has anyone encountered this issue before? If so, can you share your solution or any recommendations for fixing this issue?

Any help would be greatly appreciated. Thank you in advance.
