shader_feature in "multiple shader program variants" doesn't work on Android

I am trying to use the shader_feature in this doc. Everything works fine on desktop in editor, but when I push it to Android device, it doesn't work, without any error log.

Is this a limitation for this feature? or I'm doing something wrong?

Here is my simple test:

 Shader "Tango/YUV2RGB" {
 SubShader 
 {
     ZWrite Off
     ZTest Off
     Tags { "Queue" = "Background" }
     Pass 
     {
         GLSLPROGRAM
         #ifdef VERTEX
         void main()
         {
             gl_Position = gl_Vertex;
         }
         
         #endif
 
         #ifdef FRAGMENT
         #pragma shader_feature DISTORTION_ON
         
         void main()
         {
             #ifdef DISTORTION_ON
             gl_FragColor = vec4(0.0, 1.0, 0.0, 1.0);
             return;
             #endif
             gl_FragColor = vec4(1.0, 0.0, 0.0, 1.0);
         }
         #endif
 
         ENDGLSL
     }
 }
 }
