How to setup EasyAR Surface Tracking in Unity?

Question

Hi, I downloaded EasyAR 3.0 and using the HelloAR_SurfaceTracking scene using Unity3D. Every sample scene is works well except the SurfaceTracking scene. it Doesn't work. The 3D cube didn't appear in camera view. 

I tried everyting:
1. I put the cube below the Tracking but it Doesnt work.
2. I follow the instruction https://www.easyar.com/doc/EasyAR%20SDK/Getting%20Started/2.0/Setting-up-EasyAR-Unity-SDK.html#setting-up-easyar-unity-sdk and it says: " You need ARSceneTarget when using SLAM. It is similar with ImageTarget. " but there is no ARSceneTarget. I assume already deprecated in EasyAR 2.0. 
3. I m downgrade the EasyAR to 2.0 and also use the 2.0 key. It still doesnt work. 

Anyone can help?

Hello，

if you use SDK 3.0.1, you need to use 3.0 License Key. And the sample of surface tracking is dependent  on the  Phone model. It is recommended to use a phone with better performance.
