Huge thanks for posting this! This lead me to the answer!
Just in case I can save the next person some time, after you edit the config file mentioned above, make sure you are getting the fresh “new” version of the file instead of an old cached version like I was.
For me, even clicking “Delete cookies and site data” in FireFox didn’t give me the new file, I had to open browser dev tools (Ctrl+Shift+i), go to the “Network” tab, then click “Disable Cache”. Then I opened a Nation Note and it grabbed the new version of the file! Unchecked “Disable Cache” and closed browser dev tools.
