I can see this in meta.discourse.org, but not in our own instance. I checked and we’re both using 3.2.0.beta2-dev. Do I need to explicitly enable this behaviour in settings?
I can confirm that there’s no setting for this behavior, but it can sometimes be erratic depending on case sensitivity or if there are multiple words in the category name. @JammyDodger and I did some testing to find that it can help if you:
Type the full name of the category to make the “+x categories” option appear
If your category has multiple words, enter the first word, add a space and then the “+x categories” option should pop up
Does that help? It isn’t ideal, but we can get this fixed once we’ve tracked down all the edge cases here.
