Acrobat DC reverts to old version of saved files.
When I save over an old file (with the same name) and open it, it reverts to the previous saved version. Looks fine with all the changes done in the Preview, but the moment I open the file it is still the old version. Fine if we rename file or quite Acrobat and open fresh. So this looks like some sort of caching bug?
This bug has followed me for many years and countless updates. Adobe clearly does not care.
