Thanks, good to know. I'm clearly not a Lisp expert...
Follow attachment links works okay on my end, and, aside from a mixed

It seems to work with the recent Emacs version: GNU Emacs 27.2 (build 1,
x86_64-pc-linux-gnu, GTK+ Version 3.24.27, cairo version 1.17.4) of
2021-03-26.
So, it actually points to a mixed installation on my side.
Next time I will follow the instructions in
https://orgmode.org/manual/Feedback.html more carefully, and remind myself
of a possible mixed installation.
Thanks, again, Kyle for your answer.
Cheers,
Simon
