In my application, the navbar seems to be working correctly- the UI is showing up correctly, adjusts correctly based on screen size, etc, but for some reason, the toggle button doesn’t work. I tried inspecting element, but no errors show up. I made sure all the correct dependencies were installed, and added the correct paths to my angular.json file, however, it still isn’t working. I also redid ng serve multiple times to see if I just needed to rebuild the app again.
