Solved my problem! View PDFs in Read mode
"When you’re reading a document, you can hide all the toolbars and task panes to maximize the viewing area on your screen.
The basic reading controls, such as page navigation and zoom, appear in a semi-transparent floating toolbar near the bottom of the window.
- To open Read mode, choose View > Read Mode, or click the Read Mode button
in the floating toolbar. - To restore the work area to its previous view, choose View > Read Mode again. You can also click the collapse button
in the floating toolbar."
