On mobile, we need a navigation string at the top of the screen or a "back" button to go back to the main menu page.
the reason is that the menu is hidden, and we need a way to go back to the main lists.
for example, I went to the characters page, opened a character, edited it, and saved. Now I want to go back to the characters list. I can't press "Back" on the browser because that will take me back to the edit page. So if I want to get back to the list I need to open the menu and reselect from those tiny icons. Some of them are pretty clear (like the wiki or characters) but some are not as clear.
It looks like you're new here. If you want to get involved, click one of these buttons!
