After iOS Mojave install, can't see the pdf document, although if I choose Full Screen it is there.

Installed Mojave on my MacBook Pro.  Have never had any trouble with my Adobe Acrobat Reader DC.  Now the application opens, however I cannot see anything except the navigation bar across the top.  This makes no sense...the documents are open, but cannot be seen.  All I see is my desktop.

Not iOS by the way. That’s only on iPhones and iPad. So...do you see the file in the Window menu? If so try choosing Tile > Horizontal.
