When testing with Sonos (for example on an iPad), and there is no valid license used (for example: the end-user has an Site-license, but the site-license is accidentilly not added to the Sonos-project), the Sonos App is showing "Loading", without any further action, message or visible warning that there is NO valid license to use (in this case) the Sonos App.
If there is NO valid license found when running test-projects, commercial projects, etc, please make a warning on the panel: no valid license found. This can save much, much time for searching reasons a project can not executed.
PS: We already adviced this 3 years ago, but we didn't found it on this Forum...
