sorry for the late response, I overlooked this forum thread.
Your published game still works if the license expired, if you do the following (as described in the Publishing Guide):
1.) Set the stage property of the config.json file to publish
2.) Build your game in release mode
3.) Use RESOURCES (and qrc) for your qml & JS files. See the Felgo Demos how the qrc file looks there (you need to include all subfolders in the qrc file). We’ll also add a more detailed description to the Publishing Guide with the next Felgo Update.
Developing of the app does not work any more if your license expired.
