My point is that you need to set :

* Frame 1
:PROPERTIES:
:BEAMER_OPT: label=foo
:END:

* Frame 2
:PROPERTIES:
:BEAMER_env: againframe
:BEAMER_ref: #foo
:END:

because if you use CUSTOM_ID in the first frame, the link is not resolved.
The code at stake is :
ox-beamer:org-beamer-headline which calls ox-beamer:org-beamer--get-label
at line 624

Clearly, org-beamer--get-label doesn't make use of CUSTOM_ID.

It is a bit strange to have to use another way to set custom labels than a
CUSTOM_ID property.
