Yesterday I updated Adobe app to version 20.10.1 and right after that notice that documents are not autosaving right after signed on Dropbox.
You see, before update, I could open Dropbox, opened a pdf document, sign it, and close it and document automatically got saved.
After yesterday update, document does not autosave after closing Adobe or app.
I also have, test this on IOS and option of autosave is currently working
