File Save Options - Recovery data location
I'm running the latest version of Illustrator (26.2.1 as I'm writing this) but my data recovery preferences are somehow stuck at the location for Illustrator 20 and the application warns me every time that it can't save recovery data for the current document. I can change this, I know, but that still just keeps it then stuck at the location for version 26, and will presumably break again when version 27 is released.
What I need is some way to restore the default behaviour which would (presumably) automatically update to the correct relative location for the current application version.

I suspect this may be one of the preferences that's only saved on a clean exit - if you are the kind of person like me who always has Illu open unless it's just crashed or you're manually quitting it to update it or some plugins, then try setting this, then immediately quitting.
I just checked and mine was still saving data recovery into a much older folder too; I changed it to the latest version, then manually quit, and it's still claiming to save to the newest directory. Guess I better add another thing to the list of "stuff to do in a major version update" that I keep next to the program.
