I have created a category and a subcategory, but when I create a topic, it seems to only allow me to choose from top level categories. I was expecting perhaps another dropdown to appear afterwards that would allow setting the subcategory, but that’s not happening.
Similarly, if I try editing the topic title/category, I don’t see a way to select the subcategory.
I have the same issue here on meta (if I choose ‘extensibility’ as the category when creating a topic I don’t see any options to choose a subcategory)
What am I missing?
