Dropbox transfer has changed the default download expiration to 7 days. In the past, it has been 30 days, then for some reason, it went to 45 days, and then this past year, the default was a year. I have never changed that date, nor can I figure out how. What I do need is for the default to become more than seven days. Does anyone know how to change the default? I know how to change the expiration date every time I make one, but I don't want to do that for all that I do. I want the default to be more days.
