I recently upgraded to Illustrator 24.3 and am having a problem saving my .ai files to Dropbox. I am a long-time Dropbox user and have an excellent connection. All files upload/sync at hundreds of megabytes per second. However, since 24.3, when I save a .ai file from illustrator, it takes 10-30 minutes to upload, saying "waiting on sync." I can make a copy of this .ai file on Windows 10, and that copy syncs right away--it's only the .ai being saved directly by illustrator that is being delayed. I have tried terminating the illustrator program to see if it is holding onto the file status somehow, but that does not help.
