Windows 8.1: certification fails on "Direct3D Feature Test"


I developed a game for win 8.1, using latest cocos version (current master). It fails on certification test:

Direct3D feature level support

•Error Found: The Direct3D feature level support test detected the following errors:

•Impact if not fixed: Windows Store requires all applications using Direct3D to render properly on feature level 9_1. See the following link for more information:
Certification requirements for Windows apps

•How to fix: Ensure that your app renders correctly on Direct3D feature level 9_1, even if you expect it to run at a higher feature level. See the following link for more information:

Developing for different Direct3D feature levels

Any Ideas?


Current master being 3.0? That is alpha, not ready for production.

Not sure if that has anything to do with it or not.
