I am trying to learn how to use the library manager/editor to create a new device (a LCD display). I created a new symbol/component/package/device, following the guide in the documentation. Then I discovered that I had forgotten to add a few signals/pins to the symbol and component. I went back and updated the symbol and component, but those changes did not appear in my device. I even tried deleting the device and creating a new one, but when I selected my updated component in the library manager, the new signals/pins were not there. Am I missing something?
