As a graphic design, I use the same few .ai art files per day. duplicated into new files. For over a year, I've been able to select .ai files to upload directly into a image field in art proof form (which is also duplicated and reused over and over) that I created. This is a function that I was able to do hundreds of times over the past year.

Then after running an update to Mac Catalina on 10/31, Acrobat Pro DC no longer allows .ai files (however .eps files are accepted) to be directly uploaded into image fields. The .ai files nor the pdf forms have been changed since before or after the update.

As a workaround, I either have to save out a .jpg of each .ai file, OR add a second extension to the files, <filename>.ai.pdf to get the files to upload. Both of which are tedious extra steps. I would really like to be able to select .ai directly into image fields again.
