There is no point to adjusting "Automatically save document changes to temporary file every _ minutes." I have it set to 1 minute, but when Acrobat crashed, it recovered the document I started with over an hour ago-no saves since I started. This happens regularly, regardless if I save local or to Adobe cloud storage.
If I have to duplicate the time spent compiling my study notes, I might as well go back to physical printouts that save in real time, and scan to make searchable if needed.
