So I have set up my ACE development environment, put a confluenceThemes example into the modules section of atlassian-connect.json, installed ngrok etc etc, and started it via npm start.
After what it feels like two hours, I get the /installed POST request, it pulls the icon, I go to the dev site, install the theme (tried global and space), but NOTHING. All default colors.
Am I missing something? Doesn’t this work anymore?
