While using the full screen feature, the continuous scrolling feature which is there in non-full screen mode is not working properly. While scrolling, the page moves to the next page at the half of scrolling.
In Full-screen mode, the whole PDF page is visible on screen and single page continuous scrolling preferences are not available.
For detailed information, you may refer to Viewing PDFs and viewing preferences, Adobe Acrobat
You may use Adobe Wish form to file a feature request or raise a request for the modifications in existing features Feature Request/Bug Report Form

Hi! I asked the same a while back and finally got a good answer from @Venkat1996:
Hi, although the function is directly not available, there is a workaround for that. You go to full-screen mode and enable auto-scroll by Ctrl+Shift+H and then press escape.
Taken from my post: Enable scrolling in Full Screen Mode
Yeah, the software have the function but we don't have a button to access it. I always do this when reading which doesn't feel right
