The comment that I've gotten back several times is:
1. We do not permit skills that are directed to children to include mature content or advertising, or to collect personal information. Please remove the mature content, advertising or functionality that collects personal information, and re-submit for certification.
However the skill doesn't collect information of any kind, has no mature content, has no advertising, etc. How can one fix the issue if the tester doesn't clearly identify what the advertising, mature content, data collection, etc. actually is?
