Why can't I submit feedback with Feedback Assistant?

I launched Feedback Assistant, and signed into my Apple ID with beta access, but it won't let me create new feedback. The "new feedback" button, menu item, and touch bar item are all greyed out. The online help was useless. How can I submit beta feedback if the app won't let me?


I upgraded to today's developer beta, and it did not solve the problem.
