It would be nice to investigate about this error, it it persists. > I tried to force my own one and I was surprised CUSTOM_ID was not honoured > as it is in other backends (html). HTML is the exception, not the rule. It obeys to CUSTOM_ID because those are "public", i.e., they may appear as such in a URL. There is no such constraint in, e.g., LaTeX. Anyway, now "ox-beamer" should obey to `org-latex-prefer-user-labels' for custom ID. Regards,
