I have browsed the mailing list archives for further clues. It seems that the same issue has already been reported in March 2024: https://lists.gnu.org/archive/html/emacs-orgmode/2024-03/msg00067.html
However, I do not think that my config is to blame (see minimal org-mode config in my previous message). > Choosing `org-id-store-link-maybe` instead links > to the heading in my gtd > file where > `%%(org-contacts-anniversaries)` is called - this > is new to me and not what > I want in this case. Please ignore this part, I got confused with my own keybindings for following links vs. jumping to org agenda items. Thus, the only issue I (still) have is the unwanted prompt to select a linking function.
