We have an app which works well on iOS 9.2, it use the feature
VPN On Demand. But when upgrade to 9.3 (9.3 all versions, including 9.3.2 beta 4),
VPN On Demand just ignore
We submitted a bug to Apple and got response that There is nothing Developer Technical Support can help, you should connect general VPN support which is supported by AppleCare
I am using the same mobile configuration on iOS 9.2 and iOS 9.3 but get totally opposite result. But the document didn't indicate they have made API change. As far as I know, it should be a bug instead of an issue AppleCare can handle. We are contacting AppleCare for help and get no response yet.
I'm asking this question hoping to get some advice which Apple department I should ask for help?

google.com, it should first check
126.96.36.199 for DNS result.
It will not request
188.8.131.52 for DNS result and will start VPN connection immediately.
