Hey elliot
I use v4.1.8.1, but it doesn’t show it in the selection:
(sorry for the german, but i checked all the options and with no one you got taxonomy-options added.
Does it have something to do with translation or do i have to activate it somewhere?
edit: ah, in german it’s translated with article-relation which is a bit confusing, maybe a change to “Taxonomie” would do better, but thank you very much for your support and your patience 🙂
