 Hello
 If you install a fresh WordPress multisite without any plugins, and you
 create a subsite like mysite.com/site1 and you go to Appearance > Menus in
 the dashboard of the subsite, you come across the following problems
 although you do not have such problems with the main site's menu editor:
 (I tested with various browsers, various PCs, various OS's, on the latest
 Wordpress version 5.5.3, a fresh install without any plugins)
 1- We cannot add new items:
 We can add new pages to the menu, but we cannot add new custom links,
 posts, categories, etc. to the menu. We can add them easily to the menu of
 the main site, but not the subsite.

 2- We cannot move / rearrange the menu items:
 When we click "edit" beside a menu item, we do not see the arrangement
 options such as Move Up / Move Down / Move Under / etc. Those options are
 available in the main site.

 3- Screen Options Button Does not Work:
 When we click on Screen Options, the button does not work. It works well
 on the main site.
