I tried C-c C-x p to set property as VISIBILITY and value as folded. The output looks like this:
* Org Headline Description
:PROPERTIES:
:VISIBILITY: folded
:END:
But when I close and reopen the file, this headline still shows up in its full unfolded state. What more do I have to do to open this header in folded state?
p.s.: My emacs version is GNU Emacs 27.1.
