When previewing the bot in the editor, there is no default category but when I preview it automatically selects the first from the list. I would much rather force the user to select one so that it goes to the right category. Otherwise they don't see the dropdown and i’m having to manually get the right information to the right people.
I use 2 categories for feedback and 1 category for support issues. The feedback categories go to my product management tool, the support issue goes to our support email.
