sectioning in org-mode to beamer does not work

Question

I am trying to subdivide my presentation further into section and according to the org docs, setting

#+BEAMER_FRAME_LEVEL: 2

should allow for top-level headlines to be interpreted as sections, whereas not the second level headlines, i.e. ** are defining individual pages. However, in my minimal example below, setting the value from 1 to 2 does not make any difference. What am I missing here?

#+TITLE: Abandon all hope

#+startup: beamer
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [bigger]

#+BEAMER_FRAME_LEVEL: 2

* First page
** Stuff
larifari
** second stuff
larifari
* Second page
** fdjsfsd
larfdfj
** fjs

Answer 1

(If I understand well,) the correct way to do this is to replace #+BEAMER_FRAME_LEVEL: 2 by H:2 in the global options:

#+TITLE: Abandon all hope
#+startup: beamer
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [bigger]
#+options: H:2

* First page
** Stuff
larifari
** second stuff
larifari
* Second page
** fdjsfsd
larfdfj
** fjs
iiinfdnf

See for example here: https://github.com/fniessen/refcard-org-beamer, or directly in the current Org manual:

Org headlines become Beamer frames when the heading level in Org is equal to org-beamer-frame-level or ‘H’ value in a ‘OPTIONS’ line
