Resolved (more or less): Cannot remove Dashboard App

I was playing around on my second Hub, and installed the built in Dashboard app. When I finished, I deleted all the dashboards no problem, but can't remove the app itself. On the settings page for the app, there is a big "Remove Hubitat Dashboard" button, but it doesn't do anything. I'm running 2.1.14.119

I didn't have this problem with an earlier firmware version.

Suggestions?
