"Out of Suffix" Warning
New Adobe updates (downloaded 9/17/20) always give an "out of suffix" warning before opening a file. The problem occurs when trying to open a file for viewing and when generating a new PDF from another program. The warning is not causing issues within the PDF itself, it's just annoying to have to click "Ok" several times on this warning every time before being able to open a file. It is also unclear what the warning means or what it affects.
