Split PDF by bookmark error message read-only
Windows 11, Adobe Acrobat Pro DC Version 2021.007.20099, saving split-by-bookmark PDFs to a Dropbox folder (Dropbox permission for Adobe Acrobat is turned on).
I suddenly cannot split PDFs in Acrobat Pro DC and receive this error message "The file may be read-only, or another user might have it open..." However, if I select the target folder as "A folder on my computer" and navigate manually back to the folder, I don't receive the error message. The target folder is a Dropbox folder. This was not an issue until this week (Novermber 15, 2021). I do not have a preview pane open in file explorer and I generally work in Opus Directory. I see this question a lot online and none of the answers work. Please help!
